[FIX] website_quote: fix Sign & Confirm

Commit 7636b51 modifies the route from JSON to HTTP by mistake. Indeed,
the route /quote/accept is called from an ajax.jsonRpc request, not from
the `method="POST" t-attf-action="/quote/accept` which can be found in
website_quotation.xml.

The t-attf-action is actually only used to recover the order_id and the
token in website_quotation.js.
