Add UI to delete the role watchdog entities.

Mmm... in fact, not sure if it makes sense to have permissions to view published/unpublished role watchdog entities or edit/delete them because these are managed automatically. Maybe only the "administer role watchdog entities" permission would be enough to control access to all the CRUD tasks on these entities?

Agree

It seems these entities are just use as a storage mechanism of the role changes activity. It makes little sense a permission to control access to view, create or edit these entities. But a mechanism to delete entries maybe?

The issue has been reported basically because the module does not defined permissions that it declares in the entity class definition of tries to use in the entity access handler, which makes the permission schema incomplete, at least.

I do not see the need to view, edit or create RoleWatchdog entities, but deleting might be needed, maybe in case a role change operation has been done by error and it is needed undo the change and remove the history?

Thank you!
