Add error handling and print traceback in RFID tests

Browse Source 
The update introduces IOError specific exception handling in the RFID tests. It also prints a traceback for both IOError and general exceptions. This is done to better diagnose issues related to connectivity and IO in the tests as and when they occur. The code is also cleaned for better readability by fixing indentation and removing unnecessary comments and spaces.
