Error while trying to delete an organisation with no members

An organisation was created for test purposes, to which I was the sole member.
I removed the user from the organisation, then tried to delete it. The admin console returns the following error :
"Error deleting organisation
Error saving organisation"

I removed the user from the organisation

How did you do that? If I try to leave or remove myself from the organization I get an error message that tells me that "The last owner can't leave".

The error was probably caused by creating an Organization API Key as described in #4556, so this should be fixed now in testing.

If you manually removed a user, then i suggest to also manually remove the org, because that is the only way this could have happened i think.
