v1.0a1 AttributeError on changes_display_dict for ManyToOne relation

When accessing the property changes_display_dict on a LogEntry with a ManyToOneRelation, I get the following error: (running with Django 3.1 and Python 3.8.5, and version 1.0a1 of auditlog.)

@nanuxbe I closed it because it wasn’t supposed to be opened with the master branch. So right now there’s also a lot of other commits not relevant to the pull request. It seems like a lot of people are experiencing this issue, so I’ll open a new pull request with a proper branch and hopefully see it being merged sometime.

There’s nothing preventing this merge, as it has no impact on the code whatsoever, other than preventing a possible error.

I opened a new pull request #317

I’m having this problem too

@tudoanh Could you please give me a small example that reproduces the problem?
