fix(RD): pass copy of IndexedPack to callbacks instead of ref.

This prevents a crash in which the pack list gets updated in a search
request meanwhile a versions / extra info request is being processed.
Previously, this situation would cause the reference in the latter
callbacks to be invalidated by an internal relocation of the pack list.
