fix(loader): use false as default value for transclude in component helper

The default value of for transclude in component helper is now `false`.

The change is motivated by the fact that using `transclude: true` when not necessary
made component unusable in conjunction with structural directives that also require
transclusion such as `ng-switch-when` and `ng-repeat`.

Closes #13566
Closes #13581

BREAKING CHANGE:
Angular 1.5.0.beta.2 introduced the `module.component` helper where `transclude` was true by default.
This changes the default for `transclude` to `false`. If you created components that expected
transclusion then you must change your code to specify `transclude: true`.
