Data tracing: be able to handle const {_a, _b, ...data} = useHook() spreads

[balazsbajorics]

For these data, we currently return DataTracingFailed but instead we should return DataTracingToAHookCall. dataPathIntoAttribute should become optional, as some array cases (const [_one, _two, ...data] = useArrayHook()) are not simply addressable using an object path, and in those cases it's best to just leave it empty instead of it containing a wrong value.
