[gnome-music/wip/jfelder/artistalbumswidget-artist-property: 3/3] artistalbumswidget: Create artist GObject property

[Marinus Schraal <mschraal src gnome org>]

commit 6d20d46b4317207c275b03710f91041cd227a51a
Author: Jean Felder <jfelder src gnome org>
Date:   Fri Jun 22 16:10:01 2018 +0200

    artistalbumswidget: Create artist GObject property
    
    artist becomes a read-only GObject property corresponding to the
    artist name.
    This fixes a crash caused by commit 85066a19 (make artist variable
    private).
    
    Closes: #199
