enlightenment_remote: restore compatibility with older versions with bg-add / bg-del

Summary:
older versions of enlightenment_remote had a additional first param that did nothing
this change detects if that paramater is still passed in and ignores it. There are
a couple of applications including variety that rely on this behavior as well as some
user scripts
