MQE-570: Sanitize MAGENTO_BASE_URL (.env file) and Selenium params

- addressed all base AC of issue.
- Broke out sanitization into its own method, defined _resetConfig to prevent variables from being overwritten on test startup.
- Added step to configure rest URL based on sanitized version of MAGENTO_BASE_URL.
