Using OutstandingToken model causes attribute missing error when blacklist app is not enabled during token refresh.

[Kazhuu]

Hello! Thank you for such a nice library!

Recently we updated our Python libraries and it seems that the latest version 5.5.0 causes following stack trace when the blacklist app is not enabled for the project: https://django-rest-framework-simplejwt.readthedocs.io/en/latest/blacklist_app.html. This error happens during the token refresh. When I enable the blacklist app and run manage.py migrate, the error goes away.

It seems there should be some check in that part of the to check if OutstandingTokens available or not.

I tried to look the existing issues but did not find this being reported. I could also provide a fix for this.
