Fix python tests

Fix a Python test issue exposed by OSS-fuzz integration in https://github.com/google/oss-fuzz/pull/13874

I can reproduce this with the oss-fuzz build (by setting UBSan flags locally). I do not know why the issue only shows up then, but this fix is correct - the method signatures are the same as the Compact protocol factory. The factory is supposed to not be passed any argument, or the arguments that are passed should be the limits. This manifested as the below failure:
