Promoting users to TL2 when joining a group - retrospectively?

[Canapin (Coin-coin le Canapin)]

The groups are updated during a Sidekiq job.

The task is EnsureDbConsistency and can be triggered through Sidekiq, if you know how to do it. You can also wait a few hours; groups will be updated automatically.

I figured it out this here:

How do I promote all users to trust level 1?

I figured it out. The sidekiq task which triggers the trust level groups population is EnsureDbConsistency. After updating users trust levels from command line (either gaining or losing trust levels), EnsureDbConsistency will move users in and out from these groups.
