Fix issues where Drydock queries didn't work correctly with empty arrays

Summary: Ref T2015. This fixes issues where the Drydock queries wouldn't filter (or throw an exception) when passed empty arrays for their `with` methods. In addition, this also adds `array_unique` to the resource and lease subqueries so that we don't pull in a bunch of stuff if logs or leases have the same related objects.

Test Plan: Tested it by using DarkConsole on the log controller.
