[FIX] survey: traceback while opening multiple answer question

The above two fields, which we are cleaning up, were added to fix the
resequencing issue https://github.com/odoo/odoo/pull/108450.

The other problem that remains here is that whenever we are opening the multiple
choice question from the (survey.survey) form view after changing the question
selection field, we get traceback.

The problem was generic, so a more generic fix was pushed into the JS framework
https://github.com/odoo/odoo/pull/116561 ,which solves the earlier resequencing issue. So here we are cleaning up
 the earlier fix, which is unnecessary now. And by this issue while opening multiple
choice question also resolves.
