Current code might delete local handoff objects incorrectly
when remote node requires whole of the objects at poking
because empty cand_objs won't be applied to the delete candidate
objects list.
This patch ensures the delete candidate objects list always
will be updated (i.e. it will be empty list when the poke job
find whole local objects are required by remote), and then,
handle deleting objects correctly according to the delete
candidate.
This patch includes a test written by Clay Gerrard at [1].
