do_unbind() calls backend_unbind(), which cycles on all databases except the
frontendDB.  Typically, this is not an issue, since there's nothing to do in the
frontend for unbind; however, if a global overlay needs to install some unbind
hook, this will never be invoked.

I've fixed the problem by invoking frontendDB->be_unbind() right before
backend_unbind() in do_unbind().
