Problem Description

Update settings fails if team can not be removed from repo
due to organizational restrictions.

app/lib/plugins/teams.js

Line 33 in 97c12a3

remove (existing) {

What is actually happening

If a team has been granted permittions to the repo on an organizational level
It can not be removed. This causes team plugin to fail which stops settings update.

What is the expected behavior

If a team permission can not be deleted due to permission error
(or an error in general) it should be skipped as unresolvable.

Error output, if available
