The tick-processor tests are inherently non-deterministic. They therefore have false negatives from time to time. They also sometimes leave extra processes running. Move them to their own directory until these issues are sorted. Note that this means that the tests will not be run in CI. Like the inspector tests and other tests, they will have to be run manually when they are wanted.
