[Bug] Fees don't show if wallets are not connected

[rotemh]

Description and context

When setting a path, the fees are not been calculated. I.e. it seems like the transaction is free.

Steps to reproduce

1. Select source network, Solana
2. Select token, W
3. Select target network, Eth
4. Select amount, say 100

Do not connect wallets

Experienced behavior

It just shows that the user gets 100W, which makes it look as if there are no fees associated.

Expected behavior

I expect to see the preview panel with the fees as seen when wallets are connected.
