Fix for HHH-4646 and HHH-5177 

- Read audited properties from subclasses first, then check recursively on superclasses.
- Chech on superclasses only if a class is audited
- Calculate if the "current" class of the recursion is audited at class level.
- Created ComponentAuditedPropertiesReader subclass for AuditedPropertiesReader to use for reading component audited properties inside classes
- Created a protected method in AuditedPropertiesReader, letting the subclass do their job.
- Ordered the code to be more understandable.
