Stop showing task status if no tasks are present

Closes #33880

See merge request !12303

Closes #33912

Previously the task status would be visible even if there where no tasks
in the description. This fixes that by changing the regex to check for
tasks without 0.

This also fixes a bug where update the description inline would not
update the task status text on screen.

Closes #33880
