(core) close a hole in bundle cleanup for granular access control

Browse Source 
Summary:
A client hit a situation where a granular access control "bundle"
was not closed, leaving the document locked until reset.  I don't
yet have a replication.  This diff is a possible mitigation,
trusting various methods less.

Test Plan: existing tests pass
