Make ERP5TypeTestCase.publish() usable in live tests

A change that also applies to traditional tests is that the password does not
need to be known when logging with basic authentication. If the given password
is empty (e.g. 'ERP5TypeTestCase:'), password validation passes regardless the
actual password: to keep things secure, this exception is only valid for the
test thread and during the call to publish(). This is a simple way to deal with
random passwords in live tests.
