taskmanager: Update rootIndex when visibility is changed

When there are two grouped tasks named A and B, and the position
of B is swapped with A (by dragging B), user can still see old
items of A in the textual list of grouped tasks B.

This is because in the original binding expression, both visualParent
and itemIndex are not changed, so QML will not re-evaluate the

To only update rootIndex when `groupDialog.visible` is true,
`Binding.when` is used, and `Binding.RestoreNone` is to avoid
sudden changes in height.
