Diagnostic info added to a possible exception

if non-existing e.g. deleted/renamed class or its namespace is loaded from a model, a null reference exception is raised in called DevExpress's code; current exception (see below) has contained little info so far

Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object.
