Do the testcases pass for you with this patch? They still fail for me with
rsyslog-7.4.7-7.el7_0 and systemd-219-5.el7.

This is config used by syslogs tests:

# cat /etc/rsyslog.conf
$ModLoad imuxsock.so
$ModLoad imjournal # provides access to the systemd journal
$IMJournalStateFile imjournal.state
$SystemLogSocketName /run/systemd/journal/syslog
mail.debug      /var/log/maillog

which fails for me unless I add "$WorkDirectory" option.
I'm guessing that's needed to find imjournal.state file:
# ll /var/lib/rsyslog
total 4
-rw-r--r--. 1 root root 124 Jul  9 09:21 imjournal.state

It seems to duplicate messages for me in quite unpredictable way.
After running syslog02:

[root@ibm-ls21-04 bin]# cat /var/log/maillog
