Stan Lagun 864aa3da57 Namespace resolution error was fixed
For method invocation context of a sender object was used.
Then the current type was taken from it and class names were
resolved using namespaces of that class. However in situations
when contracted method was located in parent class that had
different namespace declarations it lead to a wrong namespaces
being used.

This commit adds information on which class has the contract
so that the sender could be upcasted to it first.
