self-handle test: use an idle to signal GetAll messagesgdbus-properties

got_all_counter_filter() runs in a separate thread, so it isn't
sufficient to write to a variable and hope that the main thread
will see it.

Unfortunately, this change doesn't seem to be sufficient either:
under load (running the Gabble tests in parallel with this test
is enough), the test still times out waiting for the variable to
be incremented...
