[FIX] sale: use website address when sending quotation by mail

When the quotation is sent by email it is still in draft state. However right
after sending it will move to sent state. This state allows the customer to see
it in its website portal. Let us then use a convenient context key used when
sending quotations by email to force the use of website address for quotation
link contained in the email.
