Fix: send override fields

[madcampos]

Add the changes field to the execute request as well as the convert request send after executing the model.

Questions still to be answered:

• Should we cleanup the changes after uploading or executing the model?
• Is it needed to send the changes on both convert and execute?

Should we cleanup the changes after uploading or executing the model?

Hmm, need to think about this. One option is to cleanup every time and hold this state on the backend. What do we do currently with optimization policy? And do we keep any other state on the frontend?

Is it needed to send the changes on both convert and execute?

I think that just execute is needed.

@odjuricicTT we don't keep any other state on the frontend, just the changes to fields and the optimization policy.

For optimization policy, we don't cleanup the value. But I think for overwritten fields it makes sense to cleanup changes as those would be applied when the model is executed, no?
