Fix for issue with DynamicClassGeneratorHelper#getNeighbourClass(CtCl…

…ass)

- DynamicClassGeneratorHelper#getNeighbourClass(CtClass) would return
  null on some occasions. This was fixed by passing the base-class for
  the dynamic class to the constructor of GeneratedClass. The baseclass
  can be used as a substitute for the neighbour-class.
- Updated CHANGELOG.md.

 - Issue [#137](https://github.com/42BV/beanmapper/issues/137) **https://github.com/42BV/beanmapper/issues/137**; Mapping a class with a getter that returns an 
   Optional, would fail, as an Optional can typically not be mapped to the target class. Fixed implementing an OptionalToObjectConverter, which handles unpacking
   an Optional, and additionally delegates further conversion back to the BeanMapper.
+- DynamicClassGeneratorHelper was removed, due to returning null, and replaced with passing the baseclass for a generated class immediately to the constructor
