Speed up integrationUISP.py

* Adds one more "is not none" check for a line that failed on my
  installation.
* Add a level of indentation to the inner "walkGraph" function,
  so it doesn't painstakingly check every node when it already
  knows that it won't pick them (for a route cost).

My testing gave the same results, substantially faster.
