Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1647781

Description of problem:
whenever user creates a repository, there are 2 audit records created:

```
Admin added KATELLO/ROOT REPOSITORY foo_repo
Added foo_repo to N/A
```
and

```
Admin updated KATELLO/ROOT REPOSITORY foo_repo
Content N/A Missing(ID: 1541672884013)
```

Version-Release number of selected component (if applicable):
6.5.0-2

How reproducible:
always

Actual results:
Content N/A Missing(ID: 1541672884013)

Expected results:
I would expect a single `create` audit with all the attributes of the repository in the record (with credentials and sensitive information masked)

Additional info:
2 records with no info in them
