Fixed a bug where changing the password of the :user factory would cause the Cucumber specs to break.

Changing the default ```:user``` password for the ```factories/users.rb``` will causes errors, because the ```user_steps.rb``` definitions uses it's own default password that only by coincidence is the same as the user factory. This will cause the Cucumber specs to fail.

I changed it to simply load the ```@visitor``` hash as options when creating a user. It seems to make more sense anyway since the visitor is used elsewhere. You could also write out the full ```password: @visitor[:password], password_confirmation: @visitor[:password_confirmation]``` but that seems clunkier.

A minor bug, but it cost me a few hours of frustration, so hopefully this will save someone else the trouble.
