path: use `get_clone_path_obj` in _getlocal We don't need to feed the `path` object to a `peer` object, but using an higher level function is simpler here (e.g. no subscript access, explicit attribute access).

path: pass `path` to `peer` in `hg init` We directly use the `path` object to build the `peer` object.

path: add a `get_clone_path_obj` function Same logic as the `get_unique_pull_path_obj` function, this give access to the `path` object directly.
