HHH-8831 improved exception message 

When having @JoinColumn in a @CollectionTable that do not point to valid columns, the message can be really confusing. These new lines will actually enrich the exception which is thrown that the problem appeared on a specific property of a specific class.

Please include this, since it is not always clear what the actual problem is with a mapping when an exception occurs.
