Subject: seen plugin: check if there's a previous action before using it
X-Git-Url: https://git.netwichtig.de/gitweb/?a=commitdiff_plain;h=c391125e75fe205056da8e7e0d31e988be37199a;p=user%2Fhenk%2Fcode%2Fruby%2Frbot.git

seen plugin: check if there's a previous action before using it

If the registry data is not an Array, there will be no 'before'
information stored, so just use the normal output.
