test: extend the reach of info_dict checking

* print the info_dict in a format suitable to easy adding to tests.json during tests if un-tested fields are detected
* make it possible to put the crc32 in tests.json if the field is too long
* complete the "info_dict" fields in existing tests
* fixed the bugs catched doing this
