fix: make task index not crash. It looks like the task.index.html page was a copy of bug.index.html. However some fields are missing from a task that is in a bug. This causes a crash when looking at all tasks if you don't explicitly select the fields to be displayed. The task links from the sidebar do explicitly select @columns fields, so the crash is not normally seen.
