Migration: Add a migration for dialer activity on upgrade to Q

* The Launchable activity for Dialer was `com.android.dialer/com.android.dialer.app.DialtactsActivity` on APIs < 29 and `com.android.dialer/com.android.dialer.main.impl.MainActivity` and thereforth.

* Not handling this causes the Dialer Icon to displace from its initial position before upgrading to
Android Q.
