[IMP] website_crm_livechat : link visitor to lead on /lead command

If an operator executes the /lead commands, the visitor was not linked to the
lead. This commit fixed that. The visitor is now linked to the lead but the
visitor does not take the lead's name.
(As '/lead leadName' creates a lead with 'leadName' as name but not as contact
name and the visitor needs the contact name of the lead)
