Regression with backpack usernames showing up for send list and send view

[trucy]

Steps to reproduce for send list:

1. Click Send from Balances tab
2. Select token
3. Enter username or address of someone you're not friends with on Backpack
4. "Other people" section returns empty array/list instead of avatars and username matches

Send view:

1. Click Send from Balances tab
2. Select token
3. Enter exact address of someone on Backpack
4. On the next screen, only the wallet address shows up, when it should be their username

I'll fix this as I think my PR introduced it, it's related to the api serving variations of snake_case and camelCase data

i.e. the api is currently returning public_keys.public_key but for the users to show it needs to be public_keys.publicKey

"public_keys": [{
	"blockchain": "solana",
-	"public_key": "aaa...aaa",
+	"publicKey": "aaa...aaa",
	"primary": true
}]
