Different cased display names for 2 trackers causes only 1 to show in trackers list

[glibbright]

Description

If you have two trackers with the same display name, but different casing, when viewing an instance under the Trackers filter on the left it hides one of them.

Steps to reproduce

1. Add two trackers
2. Change the display name of one of them to ANT and another AnT
3. Go to your instance page
4. See on the let hand side filter, under Trackers, only one of them shows

Renaming one of them causes both to show.
