LP2007591 Allow Last-Copy Delete to Create Hold Notices

Fixes an issue where attempting to create A/T events for recently
canceled holds fails becuase the cancel_time on the hold is the
pre-insert value of "now" instead of a valid date string.

Resolve the issue by fetching the post-insert copy of the hold, so it has
all of the correct in-database values, before passing the hold to A/T
for processing.
