Cancel "-clean" when latest version does not exist

[cweiske]

I made a typo in the latest version number (1.2.3 instead of v1.2.3) and now no versions are active anymore.

dtrack-cli should cancel the process if the version given does not exist.

$ dtrack-cli -url https://deptrack -clean -latest $DEPTRACK_API_KEY project-node 1.5.8
