D4636: changegroup: improve the devel-warn to specify changelog was empty

REVISION SUMMARY
  Right now, the develwarn says "applied empty changegroup" which is not correct
  because we can send a changegroup without changelog with just manifest and
  filelogs and it will still say the same.
  
  Let's fix this to say that we are applying empty changelog from changegroup. In
  future patches I am will be adding functionality to send a changegroup from the
  server without an empty changelog.
