Can't put the same user in bot users and bot admins

[MayeulC]

Describe the bug

This creates a duplicate entry in the yaml list. Unfortunately I don't have the logs anymore.

In a related issue, it is unclear how to specify multiple users as bot admins. I don't think this is supported at all.

Also, config is overwrote on upgrade, which is annoying.

Reproduced. Here's the log :
