**Describe the bug**
Things are broken yo

**To Reproduce**
Start watchtower (version 1.2.1) and get output:

```
time="2021-04-17T15:07:23+02:00" level=debug
time="2021-04-17T15:07:23+02:00" level=trace msg="created Shoutrrr URL from legacy notifier" URL="gotify://gotify.p1k.se/*******.*******?disabletls=No&priority=0&title=Watchtower+updates+on+Ketsueki"
time="2021-04-17T15:07:23+02:00" level=info msg="Watchtower v0.0.0-unknown\nUsing notifications: gotify\nChecking all containers (except explicitly disabled with label)\nRunning a one time update."
time="2021-04-17T15:07:23+02:00" level=debug msg="Checking containers for updated images"
time="2021-04-17T15:07:23+02:00" level=debug msg="Retrieving running containers"
```

A docker compose file that is obviously not a log:

```
version: '3'

services:
  watchtower:
    image: containrrr/watchtower:latest
    container_name: watchtower
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
```

**Expected behavior**
Things to not be broken
