Simplify dynamic order verification

It seems that the methods inOrderSequence() and anyOrderSequence() are pretty much useless and should be deprecated in favor of inOrder(...$calls) and anyOrder(...$calls). Of course they are needed when using older PHP versions to avoid call_user_func_array so you might want to postpone this to when you switch phony to new PHP.

Agreed, when we drop PHP <7, this can go.
