Seems like the idea was to log an overview of message types for the
currently active api calls whenever we have multiples of 100 running.
This currently isn't working at all because `len(message_types) % 100 ==
0` will only trigger if there are 100 different message types in the
counter (we don't even have that much different messages). A fix would
be to check `message_types.total() % 100 == 0`. But then, if we hover
around 100 active messages this will repeatedly trigger logs since we
decrement for each processed message, im not sure this all makes much
sense and we anyway log all received message types with `DEBUG` logs so
i decided to just drop this. If someone thinks we should keep it with
the fix or has ideas to make this a more reasonable log instead of
dropping it, let me know :)
