Update security events unit tests

The security events framework API was changed in Asterisk 10 but the unit tests
were not updated at the same time.

This patch does the following:
* Adds two more security events that were added to the API 
* Add challenge, received_challenge and received_hash in the inval_password 
  security event unit test
