Improving error readability and handling returning infrastructure.

[blafry]

When attempting to connect the wormhole-client with a cleared storage to the wormhole-server, which contains information about the peer, it returns an error:

time="2025-02-05T12:28:08Z" level=error msg="attempted peering from peer pp-bench-t-uks: error, public key mismatch"

wormhole-client hang with the following log:

time="2025-02-05T12:28:08Z" level=info msg="Log level set to info"
time="2025-02-05T12:28:08Z" level=info msg="Starting prometheus metrics server on 0.0.0.0:8090"
time="2025-02-05T12:28:08Z" level=info msg="No cached pairing response found, pairing with server"

The log should be more readable, indicating the existence of an existing peer configuration on the wormhole-server side.

How else can this issue be resolved without deleting the peers.db file?
