vulnhash: improvement tests asserts

Previously the testcases of vulnhash package does not assert the
generated hash using all the fields used to generate the hash.

This commit change the testcases to assert the generated hash with all
fields filled.

The testcase also was change to assert the valid and invalid generated
hash
