Fix feedback form on 1C-Bitrix

On the site stopped receiving applications from the feedback form. There was an integration of the form with Roistat. Theres code in the handler. First, the application goes to Roistat, and then gets to AmoCRM. It used to work. Now it doesnt work. Also, when I used to send the form, the window did not close and did not signal that the application was sent. Because of this, applications were duplicated.
