Sylvia van Os 10498ce1a4 Prevent NullPointerException in onBackPressed
This crash seems to somehow only happen on Huawei and Xiaomi devices.
While fairly rare, it is the most common Catima crash currently logged
on Google Play Console (8 crashes over the last 28 days).

While I don't understand how this would happen, I think it should be
relatively safe to assume that if the searchview is null the user isn't
currently searching so running the normal back code should always be the
expected behaviour.

// after it swipes (very small window, hard to reproduce). The cursor gets replaced and
// may not have a card at the ID number that is returned from onRowClicked.
//
// The proper fix, obviously, would involve makes sure an onFling can't happen while a
// click is being processed. Sadly, I have not yet found a way to make that possible.
