Fix more "lost" GInterface properties
Some objects are still missing properties that they are supposed to inherit from implemented interfaces.
This time it depends on whether the object was constructed from JS:
let button = new Gtk.Button(); button.action_name = 'app.do-foo'; // this works
or whether the object is picked up from a return value, method/signal parameter etc.:
let button = builder.get_object('someButton'); button.action_name = 'app.do-foo'; // doesn't work
It looks like the reason is that
resolve_impl() resolves properties lazily, but only consider GInterfaces in the
resolve_no_info() case. This MR also looks for interface properties in the other code path and adds a test that outline the issue.
