Previously, updates of the node fields from outside the form using
setFields did not trigger re-fetching the initial state, and thus
providing updated values to the form. This is to avoid unnecessary
re-renders of the form and unnecessary requests when setFields is
triggered from within the form.
This PR resets the initial state, thus triggering a re-render and
re-fetch of the initial state, if node.setFields is called from outside
the form. This preserves the performance optimization
