remote: accept a repo and name for renaming 

Remote objects are not meant to be changed from under the user. We did
this in rename, but only the name and left the refspecs, such that a
save would save the wrong refspecs (and a fetch and anything else would
use the wrong refspecs).

Instead, let's simply take a name and not change any loaded remote from
under the user.

* git_remote_rename() now takes the repository and the remote's
current name. Accepting a remote indicates we want to change it,
which we only did partially. It is much clearer if we accept a name
and no loaded objects are changed.
* git_remote_delete() now accepts the repository and the remote's name
instead of a loaded remote.
