Since #806 blacklisting fails if USER_ID_CLAIM is something other than user_id

[vainu-arto]

https://github.com/JaeHyuckSa/djangorestframework-simplejwt/blob/048bfaa4fa9208c92703b796cda96b062e7344ba/rest_framework_simplejwt/tokens.py#L268 contains the same old attempt at optimizing away a database query. This works fine as long as USER_ID_CLAIM is configured to be user_id, but if it's something else this fails. The obvious fix is to use USER_ID_CLAIM to retrieve a User object and feed that into OutstandingToken.objects.get_or_create instead of the thing which we hope to be a raw user_id.

This should be fixed in #851, @Andrew-Chen-Wang is preparing a new release and in v5.5.0 this should be fixed.

I will mark it as closed, please feel free to reopen if i missed something
