Gracefully handle null data in refresh offer message and log error

[ghost]

User reported an unhandled exception popup in v1.7.5.

Just before the issue the client did get a disconnect: b.n.p.n.Connection: proto is null because protoInputStream.read()=-1 (EOF). That is expected if client got stopped without proper shutdown.

A offer refresh TTL message should not contain incomplete data, but is possible if the network connection is interrupted. There are other examples of interrupted network messages already logged.

Fix is to catch and log the exception stack trace. Just adds a try..catch block in P2PDataStorage.refreshTTL.
Fixes #5786

If there is an alternative way to handle this, let me know. @bisq-network/bisq-devs
