1. Redirect loop 2. refresh and access tokens are locked in user field

Two issues.

1. Redirect loop

I added following values to the basic config
- Client ID
- Tenent ID
- Client Secret Value

(I also have OIDC connected multiple other services, so I am pretty sure I did not screw up)

And copy and pasted redirect URI to Azure Portal's app registration's authentication url.

Checked 'show microsoft login button on login form (Not sure why you don't support image for this, only letters..)

Also checked Enable SSO Logout

=> I can see Fields Mapping, but I left it blank
=> Roles Mapping gives me error, and I have no idea why. I did this settings w/ admin account

After that, test configuration (the gray color button) gives me 404 error.
In a fresh private mode broswer, I get a redirection loop, and eventually Microsoft rejects my login.

2. Uninstallation creates 'critical errors'
Sorry but after the failing attempt, I tried to uninstall your module.
Then, I get critical error on Reports -> Status

From that on, I wasn't able to access a number of Admin -> Structure -> most pages that calls for users (like contents types, for example)

I re-installed this module, and traced where the error comes from.
In the Configuration -> People -> account settings -> Manage fields, I can see below two entries are 'locked' in operations.

- Access Token: Field_access_token
- Refresh Token: field_refresh_token

Since these two values are 'locked', even after uninstallation, they do not disappear, and creates critical error to all configuration pages that calls 'user'.

----
I am happy to use this module if it works, but if not, please at least tell me how to make them 'unlock' so that I can uninstall without an issue.

What comes a bit more troublesome is that even after the uninstallation, I still can see two datatables for user, access and refresh, are still there.

Would deeply appreciate if removal of datatables becomes also a part of uninstallation process.
