As a system, when exporting Test Runs using the Xray Rest API, the "Test Run Assignee and Executed By" fields are returning the Username anonymized

The endpoints from Xray Rest API to Export Execution results or Test Runs are returning the Username (user_key) anonymized due to the GDPR changes in Jira Server.

Endpoints affected:

• Export Execution Results

  GET /rest/raven/1.0/testruns
  GET /rest/raven/2.0/api/testruns/

• Get Test Run

  GET /rest/raven/1.0/api/testrun/{id}/
  GET /rest/raven/2.0/api/testrun/{id}/
  

Steps to reproduce

Step	Result
Create a new User (used Jira 8.6.0)
Create a new Test Run (Assign and Execute using the new User created)
Using the endpoint: GET /rest/raven/1.0/testruns
Using the endpoint: GET /rest/raven/1.0/api/testrun/ {id}/
