Incorrect validation exception messages in QueryValidator

[shils]

In QueryValidator's validateQuery method, when a mapped field is not found for a given part, the exception message refers to the original class being mapped rather than the class being used to look up the field:

if (mf == null) {                                                                                              
    throw new ValidationException(format("The field '%s' could not be found in '%s' while validating - %s; if "
                                         + "you wish to continue please disable validation.", part,            
                                         clazz.getName(), prop                                                 
                                        ));                                                                    
}                                                                                                              

Further along, when checking for queries into @Reference or @Serialized fields, the exception message is:

format("Can not use dot-notation past '%s' could not be found in '%s' while"
       + " validating - %s", part, clazz.getName(), prop))

which looks like a copy-paste typo.

I have a branch off of master on my fork which fixes these issues; should I create a pull request?
