Docker image: Don't reload when calling "test" command

When we changed --test to automatically reload, we forgot to explicitly
avoid that in the case of the Docker image. In the Docker situation we
would typically find two separate containers during a test, the one used
for the test, and the regular container running in the background. Thus,
the test won't be able to reload the PID that's running in a separate
container / cgroups namespace.
