Fix behaviors not working when sub-types declare properties

Since commit 81867dfbf9c16d4300727a08eed9b5c6c979e0ba we have an
optimization in place to avoid the virtual meta-call when writing
properties that cannot be intercepted. Unfortunately that check did not
take parent VME meta-objects into account, which triggered the bug.
