Query times-out on "Send" null address

[James Powell]

"Send" objects are "null" addresses, and the Send method returns with no error if called on a null address. Currently, this means any Query on a null address waits its full time-out then gives a timeout error.

Change to a consistent (and quick) behaviour of returning immediately with a "QueryOnNullAddress" message (and no error).

[James Powell]

Modified both Query.vi and Query Address (Future).vi

[James Powell]

Done.
