- update zone build and add jasmine/mocha test scripts, see: NativeScript/zone.js#1
 - refactor testing and zone-js modules to work with each other
 - add generous TestBed setup helpers in testing/src/util.ts
 - add single import test helpers for zone-js patches in zone-js/testing.[framework].ts files
 - update peer deps to reflect updated zone (could peer dep be dropped since prebuilts are exported?)

chore: disable most tests and enable ones that use TestApp one-by-one
 - add test entry point script that inits the test environment for TestBed
 - list view, modal dialog pass
 - detached-loader and platform-filter-component could use feedback. see todos

chore: replace the remaining TestApp usages in test suite

 - xdescribe the failing tests.
 - I think the remaining problems boil down to `dumpView` indicating the ComponentFixture comes back with the root components, and `@ViewChild` not finding DetachedLoader by its class.
 - remove some duplication in testing utilities

chore: cleanup and remove some diff noise from a few tests

chore: remove more test noise

 - are the line-endings different on this file? :(

chore: convince dumpView and TestComponentRenderer to agree on things

 - all the TestBed tests except for the DetachedLoader ones and a single Renderer lifecycle are passing.
 - update NativeScriptRenderer.selectRootElement to find views by ID when given a selector of an id string. TestBed uses this when creating componentRefs to get at the correct views.
 - change NativeScriptTestComponentRenderer to inject only a ProxyViewContainer which mimics what TestApp did.
 - update dumpView to strip off the new "source" data attached to a view.toString() result.

chore: cleanup lint

chore: make nTestBed helpers automatically clean up test components

 - before the components were destroyed by TestBed, but not removed from the rootView.
 - maintain a list of active fixtures for a set of tests, and remove them all when the tests complete.
 - reorder to the testing utils to flow better when reading (start with test init, then before/after then render components)
 - clean up some lint.

chore: fix issue where nTestBedBeforeEach overwrote its own imports

 - Fixes the DetachedLoader tests, and makes them MUCH simpler.
 - When you configure the test bed module, you need to specify a full list of imports, because they completely overwrite the imports array that is used.
 - That's yet another reason to use the provided helper functions, they merge in the common {N} imports for you.
 - ... and some lint cleanup

chore: make renderer lifecyle test more robust

 - the first assertion is that the view after init has been called. rather than assert it, just wait for it using an observable and avoid asserting about timing and implementation specific details of the system. Specifically this removes the assumption that `app.tick()` will advance time and call `ngAfterViewInit` on the component.

chore: cleanup from review

 - re-enable all tests in karma.conf.js
 - remove some diff noise

 - incorporate changes from zone to include @panayot.cankov's drainMicroTaskQueue update
 - update zone.js deps to reference "*" for version. Ideally it would be removed, but I believe @angular has a peer dependency on it so satisfy it with a star. This is because zone.js files are prebuilt specifically for {N} so there is no need to bring them in as a dep.

 - the TestBed changes do not depend on the upgrade (after review), and given that there are strange errors, prefer to reduce the number of changes that are not strictly required.
