[PATCH] D12119: Analyzer: Fix a crasher in UbigraphViz

I don't have ubigraph installed either. The purpose of the test isn't to check as to whether we can generate a conforming/sensible ubigraph output, but to ensure that this tiny patch works and clang doesn't crash. So, I'd keep it. But if you are worried about other/unknown problems in ubigraph generator that the test might surface, then we can proceed without the test, and a ubigraph expert can write an output validation test.
