Fix issues with certain tests.

The problem was that pqViewStreamingBehavior was not using pqTimer which
resulted in the timeout happening at unexpected places during playback. Also
pqViewStreamingBehavior was starting timer after interaction without respecting
the flag that enabled/disabled streaming. Fixed that.
