Removed newsletter name from activity feed if no multiple newsletters

refs https://github.com/TryGhost/Team/issues/1563

- Check if we have multiple newsletters in the members-events-fetcher
- Pass the resulting value to the `parse-member-event` helper
- Pass the value to the activity feed table and table-row components
