WL-1742 Don’t display options that make no sense.

When a user doesn’t have to be logged in to take a survey they can’t sensibly come back to the survey and change it. Also when you aren’t required to login you don’t know the role a person is in so there’s no point in having an option for it.

I didn’t collapse the 2 statements down into one to make it a little more readable.
WL-3582 When the page is loaded disable options.

When a user comes back to edit a survey the options should also be disabled, so we do disabling when the page loads as well as when the select changes.
