WinRT: emit mediaStatus changes before state changes

Browse Source 
This makes sure all mediaStatus changes are emitted, even when some
action is done on the media player as a result of a state change.
Also, when both mediaStatus and state are changed at the same time,
make sure both variables are updated before sending the
corresponding signals.
