Ensure test-resources folder always exist before running tests

Solves issue #60 
TheProcessTestResourceTask is the tasks that generates the resources for the android instrumentation APK, not the production APK. This means that you are creating a dependency on the test resources for the application project when just the production resources are enough for the application project. only the library projects need to depend on the test resources because libraries do not generate APKs, just AARs. So your order is correct, but you are adding an unnecessary dependency.
