Xcode: Generate scheme manually, instead of letting Xcode do it

A scheme is required to be able to run tests through Xcode, even from the
command line, but Xcode doesn't auto-generate the schemes until launched
as an application. Xcode also auto-generates schemes for all our targets,
but we only need one for the primary application target.
