[gnome-music/wip/carlosg/tracker3: 66/68] trackerwrapper: Make last-played property updates go through tracker

[Marinus Schraal <mschraal src gnome org>]

commit b6a13fe9896e47b1d7c44c19b821071b5c9ed018

    trackerwrapper: Make last-played property updates go through tracker
    
    This property cannot be written back via grilo with the Tracker3 ownership
    changes. This should be stored in the local store, thus it's better to
    handle it via the trackerwrapper writeback methods.
