Subject: No need to check if `repository_ref` is present

There is no need to check if `repository_ref` is present as:
```
      @repository_ref = if repository_ref.present?
                          repository_ref
                        else
                          nil
                        end
```

is as same as doing:

```
@repository_ref = repository_ref
```
