Added workgroup admins should become group members automatically
Summary
When manually adding users as workgroup admins they are not added to the workgroup members list, which is confusing and might impact functionality.
Steps to reproduce
Add a non-member as admin to a workgroup.
What is the current bug behavior?
User becomes admin but does not appear in the members list. I didn't test whether they can access the group anyway.
What is the expected correct behavior?
Admins should automatically be members as well.

Possible fixes
Easy fix: On editing a group, let members list be merged with admin list
Complex fix: Make UI more similar to store management such that admins are selected via checkbox instead of manually having to enter their name (also here using their IDs still doesn't seem to work)
