Wallet streaming bug

[buckyroberts]

When streaming down wallet data (and other data that includes image URLs) we need to include the request in the context in order to generate the full/proper URL.

buyer_wallet_data = WalletReadSerializer(buyer_wallet, context={'request': request}).data
WalletConsumer.stream_wallet(
    message_type=MessageType.UPDATE_WALLET,
    wallet_data=buyer_wallet_data,
)
