After removing the old aboutdebugging in bug 1539461, we can rename the aboutdebugging-new folder to aboutdebugging. We should do that just before the soft freeze for 70 (2019-08-26) in order to minimize potential uplift issues.

Backed out changeset ab25abaafa1b (Bug 1566443) for es lint failure on helper-addons.js

Thanks Bogdan! Had to update an eslintrc path pointing to aboutdebugging-new that was added yesterday in Bug 1551829.
