[FIX] web: reset the dynamic domain when discarding changes

Create record A on form view, on which a dynamic domain is added by an onchange.
Switch to kanban view. Quick create a record B. Click edit.
This sends you to the complete form view to edit the record.
The dynamic domain of A is still applied.

When discarding the changes, the _domains attribute was not reset.

Example of a model on which this flow can be reproduced is helpdesk.ticket,
with _onchange_partner_project providing the new _domain.
