In a previous PR we added the `include_all_fields` parameter to `DebugWithDb` to allow it to not create spurious dependencies. This PR takes a different approach: we simply ignore the dependencies created during debug operations. This is risky as it can create incorrect dependencies, but it is way more convenient and seems like what users probably want. It also means that `DebugWithDb` has a simpler signature that matches the `Debug` trait again, which seems good to me.
