Log Message:
-----------
Fix overly-strict sanity check in BeginInternalSubTransaction that made it
fail when used in a deferred trigger. Bug goes back to 8.0; no doubt the
reason it hadn't been noticed is that we've been discouraging use of
user-defined constraint triggers. Per report from Frank van Vugt.
