phpcs and phpunit are not running from the project 'root'

[benpbolton]

Description of the bug

While working on #111 , we learned that the default composer test will fail after initial configure due to the current structure of navigating to cd plugins/[folder] before running phpcs or phpunit and the resulting folder not having proper .phpcs.xml (prefixes, names, etc) nor a proper phpunit.xml.

Steps To Reproduce

1. Clone this repo
2. run yes '' | php ./configure.php --project_name=cwp --author_name=cwp [email protected] (accepting all defaults)
3. run composer install
4. run composer test
5. Observe failures
