fix handling of connection errors

When a `see-other-host` stream-error is received we try to re-connect to
the other host. Erroneously this also started the `reconnect_timer`.
This lead to the behavior that in cases where e.g. the login failed
we try to reconnect instead of bailing out with an error.

This commit fixes the wrong behavior by not starting the `reconnect_timer`.
