Lost ability to choose self hosted github enterprise api URL (API endpoint field) in version 2.5.5.

Expect to be able to set "API endpoint" (apiURL in the config.xml) to company's git enterprise api url via the project setup.  In version 2.5.5 apiURL is always set to https://api.github.com

I'm able to work around this problem by cloning existing projects.   However, making a new project does not allow me to choose our locally host github enterprise server (the API endpoint field is gone in 2.5.5) so the project fails on repository scan since it's pointed to https://api.github.com by default instead of [https://git.company.com/api/v3
