accessTokenEndpoint quirk with django backend

[zhutcho]

Description

I spent a day trying to figure out why I was getting ERR_NO_AUTHORIZATION_CODE on iOS and ERR_AUTHORIZATION_FAILED on Android. It turns out I just needed to add a slash to the end of my accessTokenEndpoint URL e.g.

"https://dummyurl.com/oauth/token" became "https://dummyurl.com/oauth/token/"

Thought I'd post this in case someone else is running into a similar issue, as it's not immediately obvious.

Capacitor version:

TODO for myself: Check the urls for trailing / and add it if not exists while building the urls
