Custom field context endpoint does not return project-scoped fields

Issue Summary

Steps to Reproduce

1. Access a Team managed project, and go to the project settings.
2. Go to the issue type, and create a custom field (which will have the scope of the project).
3. Find the custom field with the following endpoint: Get fields.
4. Search for the custom field context using the fieldId with the ID of the custom field that was created and has the scope: Get custom field context.

Expected Results

The context result.

Actual Results

The below response is returned:

{
	"errorMessages": [
		"The custom field was not found."
	],
	"errors": {}
}
