QuoteBoardForwarder.java: don't care about reactions in the board itself

Great, we recently made a quotes board, and if a message gets 5 stars,
then it's added to the quotes board.  What happens if someone reacts from
_within_ the quotes board itself?

Add an additional condition so that message reaction additions are not
counted within this feature if the reaction is in the quotes board itself.
