Update rules for opening dialer directly.

For Q and above, we don't open the dialer in any case.
For N and below, we always open the dialer. If the device is locked then
a notification is shown which is dismissed on unlock.
For O and P, we open dialer if devices is unlocked. If the devices is
locked then we don't open the dialer and keep the notification.
