Tim Abbott 8ceb3b88ad test_tornado: Fix leaking of event queue state.
Apparently, we weren't calling the proper clear functions inside the
Tornado tests, which resulted in unexpected behavior in other tests
that were relying on the Tornado event queue system being empty.

(In this case, a new test for mobile push notifications that assumed
receiver_is_off_zulip() was always true failed after this was run).

"""WebSocketBaseTestCase is based on combination of Tornado
and Django test systems. It require to use decorator '@gen.coroutine'
for each test case method( see documentation: http://www.tornadoweb.org/en/stable/testing.html).
It requires implementation of 'get_app' method to initialize tornado application and launch it.
