lib-index: Avoid opening .log.2 file if .log was reset After a reset there's no point in trying to read the older log files. This avoids trying to open .log.2 at least for newly created mailboxes when trying to lookup log file sequence 1 (since due to some bug/feature the log files start from sequence 2).
