Remove passing tests from the chrome_public_test_apk NS filter

- TrustedWebActivityTest.launchesTwa has been fixed
- OverviewListLayoutTest.testCanSwipeClosed has the @RetryOnFailure
  annotation, so is expected to fail once in awhile (see
  http://crbug.com/943835)
- AccessorySheetViewTest.testRemovingTabDeletesItsView does not exist
  anymore at that location so wasn't doing anything
- I will monitor AutofillAssistantUiTest.testStartAndAccept to see if it
  continues to flake

Remaining tests in this file are either related to test-only
ContentMockCertVerifier issues with the WebAPK tests or expected
failures in the Features test which expect no features to be enabled.
