Logging the NonFatal error in EndpointWrite

Fixing Issue #15530 [In akka-remote EndpointWriter NonFatal exception
is not logged at error level.]
I'm not sure this is the way the remote logging is designed. It is supposed to be logged when `log-remote-lifecycle-events` is configured. The problem might be that the cause (`e`) is not included in the log message?
