`Pool not running' error

[jacob720]

After deleting the blueapi environment on i15-1, we get the following error:

ERROR blueapi.service.runner Pool not running
Traceback (most recent call last):
  File "/app/.venv/lib/python3.11/site-packages/blueapi/service/runner.py", line 96, in stop

ValueError: Pool not running

This seems to be red herring, everything still works after seeing this
