Fix the issue that onClicked event is not fired when notification title or message is clicked

This occurs because NSTextView eats up the click events. To route the
click events to the container view, override the hitTest method to
do the rerouting.

GTTF: add independent test timeout for the test launcher

Otherwise when increasing action timeout some tests actually start taking
longer (they probably sleep).

Also change test status to timeout for tests in a batch that completed but
took longer than the timeout so that the outcome is not dependent on test
order and similar factors.
