Check Gnus group names when reading from browse server

* lisp/gnus/gnus-srvr.el (gnus-browse-read-group): If the group in
  question belongs to the native server, the name has to be shortened
  before we check it with `gnus-get-info'. It might work otherwise
  with nntp, but for backends like nnmaildir that have their own
  accounting system, creating an ephemeral group won't work.
