Ensure Codacy quality report can be generated from the sbt shell


### Desired behaviour:
It should be possible to open the sby shell and run the following:
```
$ sbt
> clean
> coverage
> test
> coverageReport
> coverageAggregate
> codacyCoverage
```

The desire is that code quality issues will be available without having to create a pull request.

See the [Codacy README](https://github.com/codacy/sbt-codacy-coverage) for details.
