*Bug description*
In stage, you can see that we have a ton of left-over repositories following the naming scheme `content-non-repeatable-test-`
The `deleteRepository` function seems to sometimes fail.

*Reproduction steps*
Steps to reproduce the behavior:
1. Log in on console.stage
2. Check the custom repositories table
3. See all the left-over repositories.

*Expected behavior*
No remaining repositories sitting there.
