Old Workflow drafts not picking up latest draft version of ComputationalWorkflow

[AlasdairGray]

Due to the rename of the profile, the website is not able to pick up that the latest version of Workflow is now ComputationalWorkflow.

Discovered while fixing #444

One option would be to rename the old versions of the profile. Another option would be to add another status into the _data/profile_version.yaml data and update the logic in _includes/profile_start.html to pick up renames.

Should Workflow be marked as deprecated? Not sure what the effects of this would be on the website. Probably won't result in the desired behaviour.

Saw it was already fixed and PR submitted

The PR fixes a slightly different issue which pertains to back links from a published version to the previous. The issue here is that when you view the page of an old version it does not have link to the latest version, i.e. version 0.4-DRAFT is missing a link to the latest 0.5-DRAFT. This is because of the name change.
