Ensure Phonon MMF backend emits aboutToFinish

It seems that, after a call to CMdaAudioPlayerUtility::SetPosition,
the reported position values are slightly lower than they should be.
This, combined with the fact that the backend emitted aboutToFinish
from its timer tick slot, means that the aboutToFinish signal is
sometimes not emitted at the end of an audio clip, if the position
has been advanced by seeking during playback.

This patch adds a check in the implementation of the
MMdaAudioPlayerCallback::MapcPlayComplete callback - if, at this point,
aboutToFinish has not been emitted, it is emitted now.
