Fixed an issue where the falsing classifier wasn't used

Because of a refactor, the falsing classifier wasn't properly
used when double tapping.
In addition did we never do the same falsing check for the expand
button and the reply affordance which it now does as well.

Fixes: 68149445
Test: add media notification, double tap it / the expand affordance / the expand button
