test/vpp_ip.py: Correct usage of 'is'

* Correct 'is' (identity) usage where equality is needed '=='.
  * Change raise 'Exception' to log message and return NotImplemented.
    (see: https://docs.python.org/3/library/constants.html#NotImplemented)
  * Remove duplicate property: bytes.
  * Remove duplicate method: __eq__.
