Improve tests (#407)

* Improve tests

This PR adds some necessary tests, fixes the naming on describe
(everything was set to RandomKeyGenerator, perhaps a copy/paste
exception) and fixes the consonant/vowel alternation test, since it was
failing if the keyspace started with a vowel.

* Remove unecessary file
