It's common for developers to namespace directories with an organization or company name like this:
/user/tyler/code/@company/path/to/cta-template-custom/user/tyler/code/@organization/path/to/cta-template-custom
This convention breaks our ability to use --template file:path/to/cta-template because function getPackageInfo checks for @ before file:, falsely identifying the create react app type.
