Prevent SystemStackError when calling super in module with activated refinement

Without this, if a refinement defines a method that calls super and
includes a module with a module that calls super and has a activated
refinement at the point super is called, the module method super call
will end up calling back into the refinement method, creating a loop.

Fixes [Bug #17007]
