Change sort order of packages and packageFiles

What does this MR do and why?

Change sort order for packages and packageFiles so the corpus row shows the correct details. We want to show the data for the latest corpus. Notice that the ID is larger after the fix.

Note: the first is returning the latest package, since it seems to be the default sort order from backend

Fixes #351632 (closed)
