Bug 30646: Unit tests for Auth_with_ldap

This patch adds a unit test to the Auth_with_ldap.t to confirm welcome
notices are send when replace + welcome are enabled in the
configuration.

We also add a snippet to hide 'Subroutine redefined' warnings in this
test as it makes the test output rather challenging to read and the way
the test is written these warning are expected.
