test(transformer/class-properties): add output.js files to override…

… fixtures (#7777)

In two of the overridden text fixtures for class properties transform, there was no `output.js` file because what was overridden was just `options.json` and `update_fixtures.js` script then generated new output files using Babel with the new options.

That was fine, but doesn't work with #7771. So add `output.js` files to the these overrides too.
