Remove duplicate bundles from build products (#501)

Due to a bug in Xcode using SPM, dependencies used in internal frameworks are present multiple times in the built product. See for example:

    https://forums.swift.org/t/swift-package-binary-framework-issue/41922/3
    https://stackoverflow.com/questions/40005130/error-itms-90685-cfbundleidentifier-collision-there-is-more-than-one-bundle

This "hack" removes them from the internal framework and only includes all of them in the main application.
