Wronge scope for store

The scope for a store is not 'store' but 'stores'.  If you're going to use the contact form for ticket creation, you won't receive any tickets, because 'contacts/email/recipient_email' and 'zendesk/hidden/contact_email_old' are created with scope 'store' instead of 'stores'.
