The screen display of the heltec wireless tracker is abnormal. (#7337)

Browse Source 
The screen of the heltec wireless tracker uses the same power source as the GPS. If the GPS turns off the power during the screen shutdown period and then turns on the power, the screen will not function properly. So initialize the screen every time it starts.
