Fix AbstractLocalizableInterfaceCreator.genMethodDecl; Fixes #10205

[axeluhl]

Fixes the order of AbstractLocalizableInterfaceCreator.genMethodDecl arguments;
this reverses the arguments of genMethodDecl to their original order so that the single call matches the declaration again.

Fixes #10205

This is definitely the right fix for this specific bug, but it also calls back to my request in the initial PR that we need more tests here. I don't personally use these Creator tools, but if I were to put myself in the place of someone who did, I think I'd want to see more tests to ensure this or other errors can't happen.

At this time I'm inclined to say we should just revert the patch and re-land it when it is tested, rather than risk breakage in 2.13 for users - let it bake a little more first to be sure.

Could you update your title/description of the PR to match what the template suggested - short concise title, descriptive commit message, ends with the "Fixes..." trailer?
