VIAVI TestCenter-Automation: Handle getting changed after applying the configuration.

• When you edit a PDU in STC, *sometimes* some objects are in fact getting destroyed and replaced with new objects. • So the new objects get new handles, but it appears to the user that the handles on existing objects got changed. • Handles in STC are generated dynamically, so hard-coding them in general will not necessarily work (although you might get lucky and find it works occasionally). • We should retrieve the handle value dynamically and assign it to a variable, which can then be used for other instances
