warnings: if behind blockchain, don't show cannot afford

Browse source 
If you're replaying or syncing with the blockchain, show that error
instead of 'cannot afford', in the case of not having enough utxos
to pay for a transaction. This is the 'more correct' error to show, as
there's a chance that the funds you're expecting to spend are in the
portion of the blockchain that hasn't been synced yet.
