Lately resolving the condition here. Which would make it more consistent with the current state (active or not) of the version (which fixes #2148 too).

I think it is better to return nil for non-active versions, but returning a blank uploader for backwards compatibility.

We don't need to evaluate the condition here, like before the changes in #1351 .
We can keep all versions retrieved internally, evaluate the condition and return them only when users accesses.
