test: invert launch arg so feedback widget is injected by default

[armcknight]

Before we generate a release dogfood build of iOS-Swift as part of releasing the user feedback feature, we need to change showing the feedback widget from opt-in via launch arg, to opt-out, as that was previously the only way to show it, but we can't set launch args in the dogfood build.
