FaceDetection example code has 2x Serial.begin() statements

Description:

The "face detection" example freezes right after "camera init success" when using ap mode. The fix is simple, and the title of this PR should be a good hint. Otherwise, the example seems to be working as expected with my limited testing. I think a little testing after the copy/paste action would prevent such a thing.

Sketch:

// ArduCAM ESP32S UNO PSRAM demo
// Web: http://www.ArduCAM.com
// This program is a demo of how to use most of the functions
// of the library with esp32 camera, and can run on any Arduino platform.
//
// This demo needs to be used in combination with PC software.
// It can operation face detection and face recognition,the image through the web page to view,
// and send commands through the web page to adjust resolution,brightness, exposure time and other parameters.
// This program requires Arduino IDE 1.8.1 compiler or above
