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:

• Converter.ToManaged is fixed to obey setError consistently
• Converter.ToArray catches exceptions
• RaiseTypeError appends any existing error message
• Fixed missing information on 'No method matches given arguments' by adding the method name.

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 saysTypeError : 'int' value cannot be converted to System.Enum

Any other comments?

I added some failing test cases to test_array.py that should be addressed by a future PR.
