Remove verify-after-running of class methods.

Since iOS 9, class_addMethod and class_replaceMethod flush ObjC cache
unconditionally, which makes testing slow by a huge factor. Removing
this code avoids many such calls, and still enables mocking and stubbing
of class method, but it requires them to happen before running.
