fix: Ensure the URN when equipping emotes is using the shortened URN

[m3taphysics]

What does this PR change?

Ensures that when NFT emotes are using the long URL that are stored within the profile, the backpack treats it as a shortened url.

...

How to test the changes?

1. Equip an NFT emote & Close the backpack.
2. Exit
3. Rejoin and ensure the emotes are still assigned.
