Joey Parrish d6616a0ca4 Fix quarantined NetworkingEngine tests ...

The test flake was caused by a leaked instance of Playhead interfering
with NetworkingEngine unit tests.  The quickest way to reproduce a
failure on the networking tests was to focus the unit tests for
Playhead and NetworkingEngine and run the suite on IE11.

Playhead tests tear down the Playhead object after each test.
However, one test created two Playheads, effectively leaking one.
That leaked Playhead would continue to poll the fake video element
after the test was complete.  Polling used setTimeout.

The NetworkingEngine unit tests would mock setTimeout and show that
the engine was calling it appropriately.  However, the leaked Playhead
would also call setTimeout during the NetworkingEngine test, which
would cause an expectation on the number of calls to fail.

The Playhead tests should clean up after themselves, but the
NetworkingEngine tests should not have to mock global setTimeout in
the first place.  This change not only fixes the Playhead tests, but
isolates NetworkingEngine's use of setTimeout to a private method
which can be mocked without affecting global state.
