Continue flow after empty response from HTML node

@dceejay

a simple test would seem to show that if you ask for an array of results, and there is no match then indeed you should get an empty array.

Doh! I went back and checked my test flow again, and the selection of array mode had not 'taken'. I guess I must have moved the mouse as I selected it, or something similar, so it was still operating in multi message mode.
So @kuzmich the solution is what I had initially hoped it would be, which is to select array mode, then you can check for an empty array which indicates no match.
