Title:
  Unable to save macaroons in MozillaCookieJar() under python3.10

Status in py-macaroon-bakery package in Ubuntu:
  Fix Released
Status in py-macaroon-bakery source package in Jammy:
  Confirmed
Status in py-macaroon-bakery source package in Kinetic:
  Confirmed
Status in py-macaroon-bakery source package in Lunar:
  Fix Released

Bug description:
  Upstream bug report: https://github.com/go-macaroon-bakery/py-
  macaroon-bakery/issues/88

  See above for details, but the essential bug is that doing something
  like the following:

      client =
  httpbakery.Client(cookies=MozillaCookieJar(".cooklefile"))

      if os.path.exists(client.cookies.filename):
          client.cookies.load(ignore_discard=True)

      response = client.request("POST", url=url, json=payload)
      client.cookies.save(ignore_discard=True)

  stated throwing a traceback under python3.10:

    [ELIDED]
      File "/usr/lib/python3.10/http/cookiejar.py", line 2120, in save
        if cookie.has_nonstandard_attr(HTTPONLY_ATTR):
      File "/usr/lib/python3.10/http/cookiejar.py", line 805, in has_nonstandard_attr
        return name in self._rest
    TypeError: argument of type 'NoneType' is not iterable

  because py-macaroon-bakery creates a http.cookiejar.Cookie() object
  with the rest field set to None, causing the writing out of a cookie
  file to fail.
