[FIX] sale_management: ignore quotation template on eCommerce sales

Quotation templates feature simplifies creating Sale Order on backend.
To make the process even faster, Odoo allows set up Default Quotation Template,
which is applied automatically on every new quotation. However, it doesn't make
sense to apply quotation templates for orders created by eCommerce users.
Particularly, it leads to an error if quotation template has recurrence.

Fix by ignoring default quotation template on eCommerce sale orders.

STEPS

1. Create a sale template with a recurrence
2. Set this sale template as the default sale template in settings
3. Go to /shop page and add any product to cart that is not recurring
-> The sales order will be created with the default template's recurrence
4. Try to pay & confirm the order
-> Error when trying to make an order with recurrence and no recurring product
