 * [RegistrationCompleteFragment] is not visible to the user, but functions as basically a redirect towards one of:
 * - [PIN Restore flow activity](org.thoughtcrime.securesms.pin.PinRestoreActivity)
 * - [Profile](org.thoughtcrime.securesms.profiles.edit.EditProfileActivity) / [PIN creation](org.thoughtcrime.securesms.lock.v2.CreateKbsPinActivity) flow activities (this class chains the necessary activities together as an intent)
 * - Exit registration flow and progress to conversation list
