LP#1796971 Wait for call number and copy before loading locations
In cases where add a copy to a call number, we fetch the original
call number via async, then attach the new copy to it. Before this
commit, however, we were not waiting for the call number fetch
promise to resolve, so the copy wasn't there to use for limiting the
location load.
Since the async request is internal to a loop, one way out is to
capture that promise, then make sure it resolves before loading the
locations.
(We previously returned the copies from the internal function, but that
value wasn't being used anyway, so we don't worry about unwrapping the
$q.all() when it resolves.)
