LibGUI: Correctly call update() in ProcessChooser

After the update -> invalidate change a couple places broke when
update() was supposed to be manually called. This instance was not
marked virtual or override, which made it hard to detect. This commit
makes sure that update() on the original model is called when the
RunningProcessesModel needs an update.
