Closes #10503 It is possible for code in `beforeEach` to capture and fork a zone (for example creating `NgZone` in `beforeEach`). Subsequently the code in `it` may chose to do `fakeAsync`. The issue is that because the code in `it` can use `NgZone` from the `beforeEach`. it effectively can escape the `fakeAsync` zone. A solution is to run all of the test in `ProxyZone` which allows a test to dynamically replace the rules at any time. This allows the `beforeEach` to fork a zone, and then `it` to retroactively became `fakeAsync` zone.
