Fix regression in issue 22457 fix.

When used in the real world it can under some situations trigger
"    assert not _relpath.startswith('..'), "Path must be within the project"
     AssertionError: Path must be within the project
"

Because _get_name_from_path was not expecting to be called with the top level
directory.
