Avoid Race conditions with Distro & module nightly snapshots

There appears to be a race condition with the Drupal.org distribution packager where a distribution, such as Drupal Commons will include changes in the installation profile or Drush make script that depend on changes in a module that the distribution includes via that module's nightly development snapshot.

In some cases, the distribution's nightly dev snapshot is packaged before the contrib module's nightly dev snapshot is packaged.

An example of this is #1904506: Required modules not found..

I propose that we avoid this race condition by having nightly dev snapshots of distributions get packaged after modules and themes.

I believe we can change that in or near this query in package-release-nodes.php.
