Fix kanban:
Move invisible user_id field outside the kanban-box.
Since jQuery migration (1.8 -> 1.11), the function append has not the same behavior.
$([undefined]).append() will crash, so when Odoo whas trying to render the user_ids m2m field in kanban, that crashs.
Anyway, moving the code outside this kanban-box, will avoid to render an invisible m2m_tag.
Misc:
Escape html
concat with %s
