Prevents a ConcurrentModificationException when a notification is added while the list is iterated over. This approach is recommended in the docs: https://docs.oracle.com/javase/7/docs/api/java/util/Collections.html#synchronizedList%28java.util.List%29

Clearing the notifications is actually the end part of the larger operation done by the preceding for loop, so it should be in the same synchronized block. Doing this prevents a race condition where a notification is added, but is then immediately removed without being shown.
