This function is intentionally not cached because it is called to calculate the
unread badge for push notifications and thus the result is expected to change.
Note that this function assumes the user is a member of the room. Because
summary rows are not removed when a user leaves a room, the caller must
filter out those results from the result.
Returns:
A map of room ID to notification counts for the given user.
