NestedForm bugs

[AIC-BV]

PR covers and demonstrates three issues I currently have, when reproducing I noticed it all has to do with NestedForm:

1. Translations are going too deep wn-translate-plugin#44
2. Repeater reorder not working in a repeater with nestedform winter#715
3. Trigger events field with ^ parent selector does not work (nestedform) winter#716

1. NestedForm is being translated in jsonable field, and it conflicts with same codes outside of the NestedForm
2. Reorder is not working in the NestedForm
3. Triggers not working with NestedForm

@AIC-BV what is the reasoning or particular issue that you're demonstrating with this PR?

@bennothommo Winter Translate issue #44 as stated in PR description

[bennothommo]

@mjauvin sorry, I missed the commit (although it was a bit vague to me until you explained it).

Nevertheless, I would prefer if we have some form of description for this change, for historical clarity. @AIC-BV could you add some detail and change the title of PR?

[AIC-BV]

I added a description and changed the title
