Because we have "prefetch_related('properties', 'project')" in
MessageManager.series_heads(), "testing.ready" didn't work due to the
stale cache of Message._properties, which is built from the stale
self.properties, which in turn cannot reflect the .set_property()
updates.

Fix it with a harder invalidating code path.
