Handled exception inside FindMethod() in late bound code with method named Set_foo and assign Foo

[cpyrgas]

Was fighting to find the cause of a handled exception in a user's app, found out it's related to have a similar named method and assign. In this particular case it's harmless, because the late binding code later does find the method correctly and calls it, but it might be worth resolving this in the future, as it might be causing a problem in a different case.

Note that if the middle class is missing, the compiler does warn about having a same named method and property setter. But not in this case.

CLASS Parent
	ASSIGN Test(u)
		? "assign called"
END CLASS

CLASS Middle INHERIT Parent
END CLASS

CLASS Child INHERIT Middle
	METHOD Set_test() CLIPPER
		? "method called"
	RETURN NIL
END CLASS

FUNCTION Start() AS VOID
	LOCAL u AS USUAL
	u := Child{}
	u:Set_test() // System.Reflection.AmbiguousMatchException

System.Reflection.AmbiguousMatchException
Ambiguous match found.
