bundlerepo: don't return the peer without bundlerepo from getremotechanges

Problem:
getremotechanges would return the 'other' repo if nothing was incoming and
there thus wasn't any bundle to base the repo on. The 'other' could be a http
peer which only implement the functionality available over the http protocol.
Transplant could thus fail with
  TypeError: argument of type 'httppeer' is not iterable

Solution:
Return the local repo instead of the remote peer if there is no reason to place
a bundlerepo on top of the local repo.
