Affects Clone and Deploy build steps.

This addresses the concerns raised in #61 (comment)

[pjdarton]

This is partially duplicated by #66
That PR is just the bugfix; this one is the bugfix and a cosmetic case-change.
We probably only need one of them merged.

Could you please merge this PR as this bug is blocking us ?

[pjdarton]

At present, all merges are a bit blocked - the only person with write-access is Jason (jswager), he's largely unavailable, and neither I or Eric (elordahl) have the access required to perform merges. Jason did (briefly) reappear to say that he no longer has the necessary resources to build/test this plugin anymore and is looking for volunteers to take it over.
Personally, I'm willing to drive one release (so that my changes, which includes this one, are "in"), but I can't promise much more than that...

In the meantime, you could always go to the "Show all checks" link, drill down to the Jenkins build that tested this PR and download the .hpi file that it created from https://ci.jenkins.io/blue/organizations/jenkins/Plugins%2Fvsphere-cloud-plugin/detail/PR-72/1/artifacts
I accept that it would be better to have an official release with these changes, and I'm hopeful we'll come to an arrangement whereby we can do that, but if you're blocked by this, then you do always have the option of using a non-official release (install from the "advanced -> upload" section of the Jenkins plugin page) to unblock you until we've got a proper release.
