#destroy(*records) ⇒ Object

This fixes a bug in ActiveRecord Association Callbacks. github.com/rails/rails/issues/7618

For example ‘group.members.destroy(user)` would not call the `before_destroy` callbacks on the memberships (i.e. the through_records of the HasManyThrough association).

But we need the cache deletion to be called. Therefore, we trigger them here manually.
