Add support for the TLS Configuration Refnum to "Not a Number/Path/Refnum"

[Dataflow_G]

When a TLS Configuration Refnum is wired to "Not a Number/Path/Refnum" it always returns true, even though the TLS Configuration Refnum has been correctly created and is valid.

The idea is for "Not a Number/Path/Refnum" to handle the TLS Configuration Refnum and return false when the refnum is valid.

Seems like a bug to me.

I was hoping R&D would see it here and comment, but I think you're right that it's a bug. I suspect it's also related to this TLS memory leak bug.
