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.

#! /bin/sh

# if there are multiple trackers, d=demo t=tracker ...
# returns last one for testing that server is up. Does not test
# each tracker.
tracker=$(ps -ef | sed -ne '/roundup-server/s/^.*\s\(\w*\)=.*$/\1/p')
wget -q -O /dev/null --proxy off --no-verbose http://localhost:8080/"${tracker:-demo}"/
