Return a Validate Module failure if VI Reference output of Start Asynchronous Call in cloneable Start Module.vi is wired

[Darren]

Prior to DQMH 5, I would sometimes see developers add a VI reference output from Start Module.vi to the cloneable Main VI instance that was running:

This was sometimes convenient for the calling code, like in cases where you needed to insert the cloneable main VI instance into a subpanel or something like that. Unfortunately, you cannot use the same approach with Start Asynchronous Call in DQMH 5.0 and later. The VI Reference output from Start Asynchronous Call cannot be used for similar purposes. So you can't output the VI reference that was used to start the async call and expect your code to work the same. Instead, you'll likely want to create a request to the module that will use the "This VI" constant within the main VI instance itself to perform whatever operation needs to be done on the main VI instance. 

I propose there be a new DQMH Validate Module test that detects cases where the VI Reference output of the Start Asynchronous Call function is wired:
