The automatic_branch_deletion ruletype doesn't work properly

[rdimitrov]

The automatic_branch_deletion fails to work properly.

Minder relies on webhook events to know the state of a certain setting, like this one. Unfortunately for this particular setting GitHub doesn't provide webhook events when it is changed, so Minder has no way to know whether something was fixed or not after its initial evaluation.

The reason this is not entirely broken is that Minder can update the profile status in the following use cases:

• When the repo is registered and/or when the profile is created.
• If Minder receives another webhook event that triggers the re-evaluation for this ruletype.

Will be addressed with reminder work.
