Fix RecentChange::parseParams @return docs

Per the docs of unserialize:
In case the passed string is not unserializeable, false is returned.

Also as we can not guarentee an array was serialized in
rc_params we cant say it will always be an array...
Quite often this is just an empty string which will
result in: "s:0:"";" (not an array)....
