Using orb fails on circleci with "Invalid reference format"

### Orb version

My ``circleci/config.yml`` looks like this:

```
version: 2.1
orbs:
fossa-cli: fossa/cli@0.0.3
workflows:
fossa-integration:
jobs:
- fossa-cli/analyze
```

### What happened

It fails on circleci with the following error:

```
Build-agent version 1.0.15283-35354d0e (2019-09-09T12:09:35+0000)
Docker Engine Version: 18.09.6

Starting container cimg/base@2019.08-node
image cache not found on this host, downloading cimg/base@2019.08-node

invalid reference format
```

### Expected behavior

When I use the circleci integration without the orb it works. BTW the docs don't mention that an orb even exists. I just found this via your blog post.
