fix($route): correctly extract path params if path contains question mark or hash

The `routeToRegExp()` function, introduced by 840b5f0, could not extract
path params if the path contained question mark or hash. Although these
characters would normally be encoded in the path, they are decoded by
`$location.path()`, before being passed to the RegExp returned by
`routeToRegExp()`.

`routeToRegExp()` has to be able to deal with both encoded URL and
decoded path, because it is being shared between `ngRoute` and
`ngMocks`.

This commit fixes the issue, by introducing an `isUrl` option that
allows creating an appropriate RegExp for each usecase.
