Description of problem:
When user releases a task in task list (therefore changing it's status to Ready), he can no longer access it, because none of the the filter tabs displays it.

I would expect to see released tasks in status Ready under: Active, Group (if relevant for the group) and All filter tabs.

Version-Release number of selected component (if applicable):
6.3.x snapshot

How reproducible:
Always

Steps to Reproduce:
1. Go to task list and create ad-hoc task
2. Click Release button for the task

Actual results:
Task disappears from all the filter tabs

Expected results:
Task should be present under Active, Group (if relevant for the group) and All filter tabs, so that user can claim it if need be.
