Update player state after QMediaPlayer::EndOfMedia

Return up-to-date player state if mediaStatusChanged()
with QMediaPlayer::EndOfMedia is already received
but stateChanged() is not.

mediaStatusChanged() is always emitted first
which could cause the player to keep outdated state
before stateChanged() is received.
