On JIRA 7, Remote Test Step Defects aren't listed using the REST API GET Test Run/GET Test Run Step requests

Quick Setup:

• Make an application link between a J7 and J8 instances;
• On the J7 instance, create a Test and execute it;
• On the execution page, add a Local Execution Defect and a Remote Execution Defect (from the J8 instance) to the Overall Execution Defects, and a Local Test Step Defect and a Remote Test Step Defect (from the J8 instance) to the First Step;
• Perform the GET Test Run REST API request (e.g.: environment/rest/raven/1.0/api/testrun/?testExecIssueKey=J8RT-3&testIssueKey=J8RT-2)
• Notice that all the Test Run Defects - both execution defects and test step defects - are properly listed:

• Scroll to the Steps details section, and only the J7 Local Defects are listed <- THIS IS THE BUG*
