Updating testcase for new user login

I think the privacy checkbox was recently added…so i have made the necessary changes.

Passes when tested locally.

Thanks,

This is actually `toggle_privacy_policy_checkbox` because this will check the box if it is unchecked, and uncheck the box if it is checked. If we really want this to work as `check_privacy_policy_checkbox` we should only click the checkbox if it is currently unchecked. 

So you could either change it to have that condition or rename it to `toggle_privacy_policy_checkbox`. I think I would prefer the latter, but then you should also add an assert into the test that the checkbox is unchecked before you try to toggle it.
