Reload task list when task is removed

Instead of individually removing tasks,
ask for all tasks to get accurate list.
This method is invoked whenever user presses
back on a root activity, which causes the task to
be killed from perspective of the activity.

Test: Visually inspected, recent task no longer
disappears.
