Path of edit scheme should not working.

[Noodlekim]

Hello.

I am testing FBSnapshot for adjusting our project.
I found an issue about setting Edit Scheme on Xcode9.

When I set the path with $(PROJECT_NAME), the testing is always fail without creating recording images.

/Users/gibong.kim.ts/Downloads/RxSwiftSignup/RxSwiftSignupTests/UITest.swift:28: error: -[RxSwiftSignupTests.UITest testExample] : failed - Test ran in record mode. Reference image is now saved. Disable record mode to perform an actual snapshot comparison!
deinit SignUpViewController

So I've set paths without $(PROJECT_NAME). It is working well.
I don't understand why it is not working.

I think it is better to check this issue or modify about setting path of Edit Scheme in README.md file.
