Some `kue` Redis keys aren't prefixed

I've recently started integrating `kue` into my project and making sure it keeps Redis nice and tidy. Unfortunately, I have found a few `kue` specific keys that aren't respecting the prefix passed into `createQueue` (found via `KEYS *` in `redis-cli`):

- activeJobsTTL:lock
- promotion:lock

Other keys like jobs:complete are prefixed as expected:

- q:jobs:complete

No files or tests are named. Search the queue creation and Redis key-generation entry points for activeJobsTTL:lock, promotion:lock, and prefix handling; verify the two keys use the createQueue prefix like q:jobs:complete, then add or run a regression check using redis-cli.
