This fixes a bug introduced in the refactoring made during the work on Delta on load. The previous implementation was closing the base image stream before it was even used.

This effectively marked layers as no longer locked, which means other concurrent tasks would be able to remove them while they were still needed. So, this PR is very likely to help with #444 -- possibly solving it entirely (though it's hard to test or otherwise confirm this with 100% certainty).

The solution implemented here is simple enough: we make it clear who is responsible for closing this stream, and ensure it is closed only after it's used.
