project_version_info() is broken

[wonder-sk]

After the update to workspaces, there was a change in API and the endpoint /v1/project/version/{namespace}/{project_name} which is used by project_version_info() does not exist anymore unfortunately.

We need to fix this by using the paginated version listing:
/v1/project/versions/paginated/{namespace}/{project_name}?page={version}&per_page=1&descending=false

The returned result is slightly different - to update the response parsing code...

We need to add a unit test as well.
