[FIX] web: get next config for model loaded with values

In `web_hierarchy`, the model is always loaded with values.
However, when a record (component) props are updated, its resId can change (i.e.
if the ordering in the hierarchy view changes), therefore not only the `root` of
the model should be updated with the provided values, but the config should be
reevaluated as well since some record (datapoint) getters use it.
