Bug 10334: remove t/db_dependent/needs_user_input/* tests

t/db_dependent/needs_user_input/Auth.t and
t/db_dependent/needs_user_input/Auth_with_ldap.t seem not really useful.
If I refer to the git history, it seems that they are antiquated tests.

The first one is not compilable:
perl -wc t/db_dependent/needs_user_input/Auth.t
Can't locate override_context_prefs.pm
