copy-frameworks bug (with macOS frameworks?)

[noremac]

You can find a sample project here: https://github.com/noremac/layout/tree/punic-bug

Here is the output of punic version (I've installed via homebrew)

Punic version: 0.2.10
Python version: 2.7.10
Checking punic version...
Current version: 0.2.10, latest version: 0.2.10

1. Checkout the project (make sure you are on the punic-bug branch)
2. punic update
3. Open the project
4. Select the Layout-macOS scheme
5. Press command+u to run tests.

The build fails with this error:

Processing: "Quick.framework"
	Copying framework "Quick" to "$SYMROOT/Debug/Layout-macOS-Tests.xctest/Contents/Frameworks/Quick.framework"

On the macOS scheme, if I replace /usr/local/bin/punic copy-frameworks with /usr/local/bin/carthage copy-frameworks things build and work as expected.

/usr/local/bin/punic copy-frameworks works correctly for the Layout-iOS and Layout-tvOS schemes.

Please let me know if you would like any more information, and thanks for making punic!
