Generate a more precise error message when trying to rename a patch to the same name. This is what we get currently:

  [cel@dexter main]$ stg rename nfs_direct_wait nfs_direct_wait
  Renaming patch "nfs_direct_wait" -> "nfs_direct_wait"...stg rename: Patch
  "nfs_direct_wait" already exists

  [cel@dexter main]$
