changegroup: move non-pruning of non-ellipsis manifests to _prunemanifests()

Google has an extension that overrides _prunemanifests() and removes
nodes that we fetch using another mechanism. That broke when
_prunemanifests() no longer got called. It works again if we move the
check for "not self._ellipses" inside _prunemanifests().
