fix(widget-builder): Update table sort when field removed or modified

[narsaynorath]

When a field is removed or modified, the sort field should update accordingly. This relies on the fact that we're only going to update one step at a time (i.e. we won't update two fields through the hook in one action) and determines if:

a) a field was removed
b) a field was modified

When a field was removed, we simply reset to the first option.

When a field is modified, we look for which field that was and then update the sort to reflect that field.

I had to fix a bug in the visualize component that was updating the state directly (i.e. directly modifying the memory) instead of updating it through the dispatch method. I fixed this by doing a deep clone and updating the field then calling the dispatch function.
