    build: fix tests with UI
    
    There were errors like this:
    (test-widget:31110): Gtk-CRITICAL **: Error building template class
    'TestWidget' for an instance of type 'TestWidget': Invalid object type
    `GtkSourceView' on line 3
    
    Linking with libgtksourceview-3.0.la fixes the problem. But I don't
    really understand why.
