NuGet Component fetch from group repo does not respect repository ordering

The expectation is that if a component is present in more than one repository, the ordering of group members will determine which one is returned. Presently we just return the first matching record, regardless of the configuration, although the query executed is indeed different.
Given a hosted repository to which I've published a component downloaded from a proxy, both of these queries return the same result regardless of the group membership configuration:

select from asset where (component.name = 'jQuery' AND component.version = '2.1.4') and (bucket.repository_name = 'nuget.org-proxy' or bucket.repository_name = 'nuget-hosted') GROUP BY name
select from asset where (component.name = 'jQuery' AND component.version = '2.1.4') and (bucket.repository_name = 'nuget-hosted' or bucket.repository_name = 'nuget.org-proxy') GROUP BY name

Similarly, browsing a group repository will show the same component regardless of the group membership ordering.

Test for this condition is presently @Ignore in NugetGroupIT, and should be re-enabled to confirm this when fixed.
