fix: swaps of insufficient asset via evm

[dmoka]

The operation fails already when MM does a dry-run estimateGas(...) on the transaction. When insufficient asset is bought, on_funds is triggered where we try to retrieve the price of the fee payment asset from the multi-pallet:

HydraDX-node/runtime/hydradx/src/assets.rs

Line 174 in 8abf856

let ed_in_fee_asset = MultiTransactionPayment::price(fee_payment_asset)

But at the point of dry-run, the storage is empty, so it doesn't contain the accepted currency prices, as they are populated only in on_initialize of multi pallet.

The solution is to calculate the oracle onchain price directly instead of getting the prices from an empty prices storage of MultiPaymentPallet
