authentication_event: fix password expiration

Before this change, password event were only recorded when
preferred_number_of_last_password_to_check was set.

We also need to record password events to check for password lifetime,
so also record password events when preferred_max_lifetime_duration is
is set (also when set to 0h, but this only makes sense in tests).

testAuthenticationPolicy was not showing this problem, because tests were not properly
isolated and test_02_PasswordHistory was enabling
preferred_number_of_last_password_to_check for all other tests.
