Configured volume resize floc 1082

Fixes FLOC-1082
:question: That might be overkill; a `refquota` of `None` is still applied to a volume in exactly the same manner as a quota set to an arbitrary number of bytes and a quota that's actual defined size hasn't changed between a move from one node to another will still have that quota applied on the receiving side. so I'm not sure such a test would really be testing anything that this one isn't.
