Unexploded archiving only archives the first logfile

[jonsyu1]

Repro steps:
Configure seelog with archiveexploded = "false". Here's mine: <rollingfile formatid="ourlogStdout" type="date" filename="./var/log/axiom.log" datepattern="2006-01-02_03:04:05" archivetype="gzip" maxrolls="1" archivepath="./var/log/axiom.log.tgz" archiveexploded="false"/>
Run logger for a few minutes

Expected: archive includes more files over time

Actual: only original file is included in archive
