When importing JUnit results to an existing Test Execution, it should be possible to send a JSON file with information for the newly created Tests.

Currently, to update a Test Execution, the single endpoint should be used to pass the key of the issue; however, this would not allow sending a second file with Test's information.
The other alternative is using the multipart; however, this does not allow to pass the key of the Test Execution.
