Fix the linting errors, from the Prettier auto-formatting, that ESLint --fix couldn't handle

This patch makes the follow changes:
 - Remove no longer necessary inline `// eslint-disable-...` comments.
 - Fix `// eslint-disable-...` comments that Prettier moved down, thus causing new linting errors.
 - Concatenate strings which now fit on just one line.
 - Fix comments that are now too long.
 - Finally, and most importantly, adjust comments that Prettier moved down, since the new positions often is confusing or outright wrong.
