Creating a Business project through the REST API do not configure Category Field context correctly

Issue Summary

When you create a Business project through the REST API and you do not set a template then the category field context is not configured

Steps to Reproduce

1. Create a project in the REST API without setting a template("projectTemplateKey": ) in the request body.
2. Try to create a new category on the Project List view.

Expected Results

• Ability to create new Categories regardless of the project creation method used.

Actual Results

• Category Field Contexts are not being created.
• When a new Category is created the following error is seen : 

  "message": "Project Specific field config for this project and issue type does not exist",
  

• The category is not created.

Workaround

1. Create the Business projects from the UI
2. OR specify the template in the request body, for example: 

   "projectTemplateKey": "com.atlassian.jira-core-project-templates:jira-core-simplified-process-control"
   

Note: The second workaround does not allow to set to customized Project Schemes to be used.
