Order results when using pagination - take 2

[c0c0n3]

Describe the bug
#208 asked to order result sets when using pagination. PR #212 implemented most of the needed fixes but left out just a couple of things in the middleware

• https://github.com/orchestracities/anubis/blob/master/anubis-management-api/anubis/middleware/operations.py#L68

This issues is just a reminder to fix up those two functions when we have time.

The middleware queries involving pagination order their result sets.
