Partially reverting Icb809274f9f63. The broken :A: prefixed passwords generated by MW before that change were apparently written back to the database -- there are 2.5M in enwiki alone. Accepting them should not depend on $wgPasswordSalt, which is a deprecated global and should soon be removed. Change-Id: I772de0fb17245d080eb15a7d5df6bf3125e1f71a
