Emit mediaAboutToBeRemoved() before mediaRemoved() in QMediaPlaylist.
When a new playlist's mediaObject is set, the content is cleared and the
mediaRemoved() signal is emitted without a former
mediaAboutToBeRemoved(). This is an issue for QAbstractItemModel
implementations, like the coming QDeclarativePlaylist, which call
beginInsertRow() and endInsertRows() in the respective signal handlers.
