py3: ensure the HTTP password manager returns strings, not bytes

The digest handler calls into the password manager on its own, and it apparently
expects strings.  Perhaps the Basic authentication handler didn't hit this
because of its manual password fetch and format in retry_http_basic_auth().

The `pycompat.bytesurl()` on the user and password just above the first url.py
diff seems unnecessary, because the password proxy in ui is converting to bytes
IIUC.
