The TestTextFileEditor doesn't use editor contribution anymore.

This is because not every test disposes its code editors correctly and leaking contributions (like the `FoldingController`) have weird side-effects (still listening etc). Also, tests at the workbench level don't need editor contribution and editor construction is faster without them
