The Xray Test Case importer is not validating if the Test Type custom field is correctly configured for the Test issue type context.

The Xray Test Case importer is not validating if the Test Type custom field is correctly configured for the Test issue type context. Not having this validation done is resulting of an error when trying to import the Test Cases and the cause can be difficult for the user to find.

A validation should be done and a detailed message should be displayed to the user if this custom field is not correctly configured.
