Thanks, it was indeed missing password + confirmation causing the
ROLLBACK.

irb(main):004:0> user.errors
=> #<ActiveModel::Errors:0x29fe1b30 @base=#<User id: 1, name: "Example
User", email: "exampl@railstutorial.org", created_at: "2013-05-12

@messages={:password_confirmation=>["can't be blank"], :password=>["is
too short (minimum is 6 characters)"]}>

has_secure_password must be something new in Rails 4. It does
everything validates_confirmation_of does.
And attr_accessible also seems to have become a thing from the past.
