Subject: [PATCH] [FIX] web_kanban: prevent crash when grouping some fields

The kanban view was changed recently to display the tooltips in column
headers.  Sadly, it appears that the developer forgot to take into
account the case when there are on tooltips.  This commit fixes this
unfortunate oversight.
