Unit test target TEST_HOST values use `debug` for all configurations

[armcknight]

I'm hitting a bug with fastlane where it can't build/run a test target because of the TEST_HOST setting value:

Reason: Could not find test host for ServicesIntegration: TEST_HOST evaluates to "~/Library/Developer/Xcode/DerivedData/<redacted app name>-gmyfcakdlvzgwyfrmtlureaezdpc/Build/Products/Develop-iphoneos/debug-<redacted app name>.app/debug-<redacted app name>"

Notice the Develop and debug there... there's a configuration mismatch.

I looked in the build settings and noticed that for all configurations, TEST_HOST has paths that contain debug. Is this correct or should they be changed to contain the values of PRODUCT_NAME in the app target? This would involve us requiring to abstract that into a user-defined setting like {{ cookiecutter.project_name | replace(' ', '') }}_PRODUCT_NAME which we'd reference from PRODUCT_NAME and use to construct the TEST_HOST paths.

Changing it to the actual PRODUCT_NAME of our app target fixes it on my end.

It could be that since someone had changed the values of PRODUCT_NAME at some point in my project, not updating the TEST_HOST values caused this drift that ultimately wound up as a build error.
