[FIX] web: show warning on create onchange

When you create a new record, you will have in this order:

- default_get
- onchange (can trigger a warning)
- _pushController => close all dialogs since ea2207afea

This is an issue since the possible warning is directly hidden to the
user.

Without the change, the added test failed with:

 Warning modal should be opened
 "executing a window action with onchange warning do not hide it":
 Found 0 elements to click on, instead of 1
