Improved PushNotificationService to support changes on Android API 26+ that require the use of a NotificationChannel. This change is only activated by the build server when targeting sdk 26 or higher. In addition, this change only applies to devices that don't have Google Play. The rest of the fix for push notifications in API 26+ (e.g. for Google Play devices) is part of the build server, as it generates the PushReceiver class which is used by google play devices.
