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.

+Merge changes from devel template task.index.html (optional)
+------------------------------------------------------------
+
+The devel template's ``task.index.html`` has some fields that are not
+defined in the schema. It looks like it was originally copied from the
+``bug.index.html``. If the task index is requested without specifying
+the columns/fields, the template will crash trying to display
+``severity`` and other fields that don't exist in the task schema.
+
+In normal use, the left hand menu for tasks always specifies valid
+columns so you may not see this issue. However if you remove the
+``@columns`` query parameter, you can see the error.
+
+The removed columns are: severity, versions, keywords, dependencies.
+
+It is also missing the ``solves`` field which is added to match the
+schema.
