Do not try to complete flush operation if stream has changed.

There is a problem when sound effect already has a sound loaded and
we try to load new sound with setSource().
When sampleReady() is called between emptyStream() and emptyComplete()
it unloads the current stream and creates a new stream.
As a result pulse audio crashed in emptyComplete() while calling
pa_operation_unref(pa_stream_cork(
m_pulseStream, 1, stream_cork_callback, m_ref->getRef()))
with the new m_pulseStream.
