Change Ben's dev account to an org so Ingo can deploy to device

`LC_ALL=C find ios/Echt.xcodeproj/* -type f -exec sed -i "" "s/DWB7DKRZ7D/Y9AF3JTNBU/g" {} \;` - that trick no longer works to deploy to my iPhone via XCode. While I could just deploy the JS code via CodePush and use your Testflight app, that means I need to push code that might potentially break your app as well just to test something out on the device - so not entirely workable.

I'm not quite sure what changed in the meantime - I suspect that the app is now assigned to a [team provisioning profile](https://developer.apple.com/library/content/documentation/IDEs/Conceptual/AppStoreDistributionTutorial/CreatingYourTeamProvisioningProfile/CreatingYourTeamProvisioningProfile.html)

> If you enter information about your app and assign a team to your app, Xcode creates the necessary signing identities and provisioning profiles for you. Specifically, Xcode creates a team provisioning profile that allows your app to run on all your devices and use app services.

@bnolan Do you think you could [convert](https://www.quora.com/Can-you-switch-an-Apple-developer-account-to-a-company-from-an-individual) your individual dev account to an org -> https://developer.apple.com/contact/submit/ (select "Enrollment Status")

More details on my current setup






Start by reviewing ios/Echt.xcodeproj and the current Apple team provisioning setup described in the issue. Confirm whether the existing developer-account and signing configuration still permits device deployment; done means Ingo can deploy the app to an iPhone without pushing unverified JavaScript through CodePush.
