Main purpose of those tests is testing serialised output of PAST/POST 
nodes. So checking internal structure is not what we want.

Currently I'm thinking about two options:
1. Adding "stream" parameter to "_dumper()" and check output in PIR.
2. As moritz++ suggested, sort keys in _dumper before output.
