Remove counts from notification page

The counts on the notification page will only ever show 1 thing. Which
feels like overkill, especially if you’re only sending one-off messages.

It’s also confusing when you come from the job/activity pages which
have one set of numbers to then be confronted with a different set of
numbers.

The important stuff on this page is:
- what the message was
- some meta information about it

Sorry Leo 😢
