mgr/DaemonServer: remove any upmaps on merging PGs

Remove any pg_upmap[_items] on pgs that are merging to ensure that they
land on the same OSDs.

This is a bit sloppy: we *could* set the source upmap to match the target
upmap (vs potentially moving both PGs to a third location, and/or then
having the balancer move the resulting PG somewhere else again), but for
now assume upmaps are not a common case and Keep It Simple.
