Fixing 846 without tests. (#1183) 

Fixing "Optimizing: -nan%... #846" https://github.com/googlecartographer/cartographer/issues/846.
The issue was triggered in a multithreaded execution, when all nodes were processed, but the working queue was still non empty (having other kind of jobs).
Unfortunately I failed to reproduce the bug in tests, so no new tests were added.
