   ## What is the purpose of the change
   
   This pull request fixes bug with creating TypeInfo for POJO Classes with generic superclasses which has fields of that genric type. The problem is when we building typeHierarchy for Pojo with generic superclass we already have values in typeHierarchy array, we stopped building typehierahy and coud not extract type for fields later.
   
   
   ## Brief change log
   
     - Removed condition on if typeHierarchy <= 1. Changed to simple else statement cause we shoudn't stop building type hierarchy.
   
   ## Verifying this change
   
   This change added tests and can be verified as follows:
   
     - Added *PojoParametrizedTypeExtractionTest* test that validates that TypeInfo for generic field correctlly exctracted by TypeExtractor
