What does this implement/fix? Explain your changes.
This change produces more specific error messages by passing setError=true to Converter.ToManaged whenever possible, such as when there is only one method in methodbinder. To support this:
Does this close any currently open issues?
No, but it provides more information to the user when they come across issues like #1099 . Instead of "No method matches" or "No match found" it now says
TypeError : 'int' value cannot be converted to System.EnumAny other comments?
I added some failing test cases to test_array.py that should be addressed by a future PR.
