How to reproduce:
1. Create a new project for standalone OSX platform
2. Set a custom bundle identifier for example "com.com.test" in Player settings
3. In the Build Settings enable "Create Xcode Project" and press Build
4. Open generated Xcode project and notice the bundle identifier is "com.unity3d.New Unity Project"

Expected: generated Xcode project copies the Bundle Identifier from the Player Settings
Actual: Xcode sets new Bundle Identifier "com.unity3d.New Unity Project"
