provided:dependencyBrowseGraph doesn't include non-provided dependencies

[dankolesnikov]

I am not sure if this is considered a feature or a bug by the library authors,
When running sbt provided:dependencyBrowseGraph with sbt of 1.3.4 and sbt-dependency-graph of 0.10.0-RC1, I am not seeing any dependencies that aren't with provided keyword.

To elaborate on my concrete use case, I am looking to see all transitive dependencies of the project including everything that is brought in by the deps with provided keyword like Spark in order to make it simple to troubleshoot runtime issues of NoMethodFound / NoClassFound.

Cheers!
