Fix display of room notification debug info (#12183)

* Fix display of room notification debug info

 * Add 'one' string because apprently it just displays nothing at all
   if that's missing, rather than erroring or falling back to use the 'other'.
 * Simplify and always display the count: it's debug info so it's best to
   be very explicit anyway, plus simpler code & one less string.

* Update snapshot
