fix: only show account warning when Geth will actually start

Before, we checked if the network was a testnet or mainnet and
warned if there were no account sconfigured to sync. However, that
didn't take into account that we could connect to an external node,
hence not starting Geth at all.
So to fix that, I moved the condition and message to the Geth module
and only log when we start the node and the condition is met.
