it does not run with activerecord over 4.2.0

SEE ALSO: https://travis-ci.org/walf443/activerecord-mysql-unsigned/builds/48597097

it may be caused that activerecord changed ChangeColumnDefinition class definition since rails/rails@3c10043bc27.

hmm. This fail does not related to my problem.

I got

superclass mismatch for class ChangeColumnDefinition (TypeError)

I used it with activerecoard-with mysql-awesome gem.

Failing test seems to related to rails/rails@7c6f3938de

Can confirm this prevents creating new records with unsigned integers in ActiveRecord 4.2
