Subscribe to group permission is disabled

MR43 Removes setting #disabled for default roles, it only sets them for the admin role.

Also if I'm not mistaken, there isn't a need to set the default value here, the defaults for each permission have already been populated.
Without doing this, permissions that have a default role to able to be unchecked.

This allows me to uncheck the "subscribe to group" permission for non-members.

Thanks, @loze. Can you please attach a screenshot showing what has changed?

Also, could you add tests to the MR?

here is a screenshot of the checkbox becoming active after the patch.

Unfortunately, I'm not really sure what to do for adding a test. Hopefully someone else can help out with that.

I encourage you to give it a try, I'm around to support you if needed :)
