stop setreminder flickable flicking in portrait mode

When setting a reminder in portrait mode after commit 8724f551 flickable is flicking. Because one has to slide up and down to pick a time, the page does flick all the time.

Applying flickableDirection: Flickable.AutoFlickIfNeeded does solve this problem.

Please test. When I first tried to fix this for some reason it would not accept this and kept flicking. After removing and reinstalling the app it worked on the first attempt. May have been my local install or not cleared cache or something ...
