Use FastNoSuchElementException on TraverserSet.remove()
A JMH microbenchmark on a TP3 traversal that hit thousands of vertices
showed the use of exceptions for flow control in `TraverserSet` as a hotspot.
Using `FastNoSuchElementException` dramatically improved the performance of the
benchmark.
Thanks to @danielthomas for identifying the root issue and providing an
initial patch.
