typing: fix forward reference in _Tlocalstr type bound

AFAIK, a quoted string in type position is translated to its ForwardRef.

This fixes the following error:

  File "mercurial/encoding.py", line 38, in <module>: Name 'localstr' is not

        )
        cov = coverage.coverage(data_file=covpath, auto_data=True)
