Can't delete read-only delegate

[de-es]

Steps to reproduce:

1. Add a delegate (don't check "Give write access?")
2. Delegate is added correctly.
3. Click Remove button
4. Confirm with "Yes" button
5. Nothing happens, delegate is still listed

When giving write access while adding, I can remove the delegate as expected.

Hi @de-es

This is indeed a bug and I have identified the cause. I am working on a fix right now

Thanks !

If you have a moment to test it (on master), that'd be welcomed !

Works like a charm. Thank you!
