fixes pluginsEnterStats

Initial implementation of pluginsEnterStats was incorrect, because I got
the foldLeft wrong, making it perpetuate the initial value of stats.
This worked fine if zero or one macro plugins were active at a time,
but broke down if there were multiple of such plugins (concretely,
I discovered this issue when trying to marry macro paradise with scalahost).
