Asset selector will not load until long queries complete

[ValarDragon]

The asset selector icon on the Swap page will not load until this query completes https://app.osmosis.zone/api/edge-trpc-assets/assets.getUserAssets.

Theres two problems:

• That query takes insanely long in non-EU timexone (1.35s in very good internet in korea)
• We should not be blocked on this query for the asset selector. Its preferrable to have the icon load first, and then have clicking it have a delay. This at least makes the UI feel stable faster, and pipelines the latency for a user click on the selector.
