Bug: Artifact.getClient() returns null

[mivola]

I have a setup where I traverse the whole way from a JenkinsServer to an Artifact (via Job & Build) and all model elements except the Artifact return a proper value for getClient() - the Artifact returns always .

Could you rebase that against current master....

[mivola]

@khmarbaise I tried different ways to do the rebase (https://goo.gl/MExQn1, https://goo.gl/16tES9, https://goo.gl/oJFPKl), but I always end up with a merge. Can you explain how to properly do the rebase?

@khmarbaise I'd prefer to get the other Pull Requests (#380, #381) merged before I continue working on other issues ...
