First DB schema migration in Pike ensures that all of the Ocata's data migrations are completed (Iab993f93b4145a67ec2d6144acc61f2105586b3c). We can then remove them from Pike's code. The commit also removes checks that were being made in user messages code. These are not needed as we're sure everything's migrated. Change-Id: I882e953800c4f4473f175779b6a44ad55928db65
