Caolán McNamara ebe57117c4 leaks of OCollection in dbase import
presumably since...

commit 5c7b954935
Date:   Mon Jan 29 13:28:44 2018 +0200

    loplugin:useuniqueptr in OTable

OCollection has a unique and nonstandard acquire/release which forwards
to a parent cppu::OWeakObject. So when it would appear to a casual
observer, who assumes that it has an internal refcount, that its
refcount would drop to zero and then get auto-deleted, nothing of the
kind occurs.
