Fix baseConfig option for iOS

When `--baseConfig` option is used for `tns platform add ios`, the command fails with ENOTEMPTY.
The reason is that we copy the baseConfig file before creating correct directories and when we try to rename __PROJECT_NAME__ dir to real project name, it fails as we have already created this dir.
