Being added to group_creators requires logout and back in to create groups

[gene1wood]

Describe the bug
When a user accepts an invite into the group_creators access group, the user can't then create groups until they log out and back in.

To Reproduce
Steps to reproduce the behavior:

1. As a curator of the group_creators group, invite User A
2. Log in as User A and accept the invite
3. Go to /a/ to create a group

Expected behavior
The ability to create a group (the create group button)

Actual behavior
User A sees an error more_groups_trust_required

@fiji-flo I saw this behavior again today, however in this case

1. Added the user to group_creators
2. User logged out of sso.mozilla.com
3. User logged back into Auth0
4. User clicked the "Create Group" button and filled out the form clicking "Create"
5. They saw the ag_api_errors_more_group_trust_required error message.

I've searched the code base but don't see this error text (or subsets of it)
