Removed other BeansWrapper related classes that DefaultObjectWrapper doesn't use. This includes ModelCache and related classes, because DefaultObjectWrapper has only used the cache for "generic" classes (because that's where it has fallen back to BeansWrapper.wrap), which is inconsistent and doesn't worth the caching overhead and complexity.
