taskmanager: Prevent useless component creation/destruction for grouped tooltips
The binding of model property of DelegateModel in ToolTipDelegate.qml
will trigger useless component creation/destruction when rootIndex is
changed but is not undefined. Make the ternary operator depend on
hasRootIndex bool property to avoid that.
In Task.qml, only assign different values to parentTask and rootIndex
to avoid unnecessary component creation/destruction for the second time
hovering on the same task.
