Description of problem:
A Warning for using pre-v6 syntax isn't issued when it should be and vice versa.

Version-Release number of selected component (if applicable):
rsyslog-7.4.7-1.fc21

How reproducible:
Always.

Steps to Reproduce:
$ cp /etc/rsyslog.conf{,.bck}
$ cat > /etc/rsyslog.conf <<EOF
$modload omjournal
*.* :omjournal:
EOF
$ systemctl restart rsyslog
$ grep "rsyslogd-(2207|2215)" /var/log/messages
Jan 16 06:22:13 rhel-7 rsyslogd-2207: error during parsing file /etc/rsyslog.conf, on or before line 2: errors occured in file '/etc/rsyslog.conf' around line 146 [try http://www.rsyslog.com/e/2207 ]

$ sed -i -e 's/:omjournal:/:foo:/' /etc/rsyslog.conf
$ systemctl restart rsyslog
$ grep "rsyslogd-(2207|2215)" /var/log/messages
Jan 16 06:22:13 rhel-7 rsyslogd-2215: omjournal supports only v6+ config format, use: action(type="omjournal" ...) [try http://www.rsyslog.com/e/2215 ]
Jan 16 06:22:13 rhel-7 rsyslogd-2207: error during parsing file /etc/rsyslog.conf, on or before line 2: errors occured in file '/etc/rsyslog.conf' around line 146 [try http://www.rsyslog.com/e/2207 ]

Actual results:
The warning is displayed for actions other than ":omjournal:" and not when they should be.

Expected results:
The reverse of the current state.
