[cuegui] Fix CueJobMonitorTree not refreshing on property changes

When job properties (priority, progress, etc.) changed without adding or
removing items, the UI would not update. The _processUpdate method was
only calling redraw() when the item set was unchanged, which only
triggers a visual refresh without updating the underlying item data.

Now calls __processUpdateHandleNested() to update item data before
redrawing, ensuring property changes are reflected in the UI.
