Fix crash caused by null parameter passed to CameraServer.add_feed() 

Fixes #46181

CameraServer.add_feed() takes a CameraFeed object type as parameter.
Passing in another type of data while binding the method it will make
tha parameter null.
Added a check for null which returns from function and does not make the
engine crash anymore.
