Fix runner startup.sh tests

- `should_work_use_disable_once_switch` was failing since the support for --once has been removed a while ago. Removed the test.
- Added `cd` before running `startup.sh` for access to the logger.sh library from within the script
- Included the runner directory into `$PATH` for access to `update-status` from within the script
