PURPOSE

Some business inquiries end up in the Helpdesk pipeline by mistake. There
is no direct way to convert those tickets into leads.

SPECIFICATIONS: PARTNER PHONE ON TICKET

This commit adds phone field to helpdesk ticket. It is a stored editable
based on partner phone field. If a partner is set it populates the phone
field.

When converting a lead to a ticket, more information is propagated. Notably
partner_name and partner_phone are now synchronized with lead specific values.

Default ticket creation message is also changed by an "origin link" one.
It allows to know ticket comes from a lead.
