builder: Fix parsing of mixed declarationsfix-builder-parsing

The GtkBuilder parser constructs the object e.g.
when handling a <binding> element. There may be
more <property> elements after it, which we were
just not applying. Fix that by always applying
property when we see </object>. To do that, we
need to track the applied status per property.

Test included.

Fixes: #4208
