    mpris: Fix lastUsed metadata
    
    Commit 39608d44 highlighted a bug which was never triggered before:
    the lastUsed metadata is badly formatted. Indeed, the last_played
    method of Grl.Media returns a GLib.DateTime. This date needs to be
    formatted into a string in order to be used by MPRIS.
    This bug had never been encountered because of the presence of a
    try/except block.
    
    Fix the issue by formatting the date into a string in ISO 8601
    format.
    
    Closes: #294
