Fix incompatibility with rack-test 2.0

[juno]

This fixes the following error when calling expire_cookies with rack-test 2.0:

     NoMethodError:
       undefined method `cookie_jar' for nil:NilClass
             @rack_test_driver.browser.current_session.instance_variable_get(:@rack_mock_session).cookie_jar
                                                                                                 ^^^^^^^^^^^

See rack/rack-test#297 for details about rack-test side changes.

I know that this gem has abandoned, however hope this helps for others.

Hello there :)

The above solution fixed the issues created from undefined method cookie_jar for nil:NilClass When do you think this will be released?

Many thanks frens 🥇

p.s.
this also seems to fixed my tests :)
@rack_test_driver.browser.current_session.instance_variable_get(:@cookie_jar)

Just FYI that accessing cookie jar directly from the current_session isn't backward compatible but I assume this will not be a problem 🤷

@nruth I think this should be released soon, we were also stumbling over this as we did not have rack-test locked and since we had to upgrade rails due to the latest CVE, we ran into this issue. Sure this will happen to more ppl. Thanks for the fix/review @juno @emresimtay

[nruth]

Looks good. BC isn't a problem, it'll be part of a major release.

@nruth Thank you for releasing quickly! 🎉
