Its a minor thing but the daemon's output looks like this when there are
no containers to load:
```
INFO[0001] Loading containers: start.
INFO[0001] Loading containers: done.
```
That blank line (or more correctly, the \n) is unnecessary when
there are no containers to load since there is no `.` printed
