Cloak with changeset issue - (UndefinedFunctionError) function Cloak.EncryptedBinaryField.equal?/2 is undefined or private

@stefanchrobot @al2o3cr I did the same thing of incrementing it step by step.
It did not work then as well.

However there was a data migration when we upgrade it from 0.6 to 0.7, which I did not perform.
As I did not have much time, I would look into this later.

Thanks for the valuable suggestions.
