Move ManifestCreatorCache tests to a separate class and remove override of equals and hashCode methods in ManifestCreatorCache

Browse Source 
These methods don't need to be overriden, as they are not excepted to be used in collections.
Also improve the toString method of this class, which contains also now clearFactor and maximumSize attributes and for each operations.
