Fix behaviour for logged-out users

Some of the edit buttons for fields in tasks were displayed for users
who were logged out. They could then try to edit things, only to get
a 401 or 500 error several steps later. This patch hides them. Task
titles were duplicated; this patch should fix that, too.
