Title: Put preventative wait for app_update_notification 

It is my belief that the app update is sometimes sliding down just before the "Clear all" is tapped and that is causing the test to fail sometimes.

This is not ideal but I'm reasoning for prevention until we can disable the app updates completely.

`master` -> tested and OK
`v1-train` -> tested and OK
