When importing Test results, some behaviours are inconsistent with older Xray Versions

When importing Test results, some behaviours are inconsistent with older Xray Versions:

1) When updating a Test issue, the Issue is assigned to the user that done the import - Expected: When updating a Test, the "assignee" should not be changed.

2) Labels are being "set" and not "added" - Expected: When updating a Test issue, the old labels in the Test issue should be kept and we just need to add the new ones.

3) When updating a Test issue, if the old issue is a Manual Test Type, the update changes the Test Type to Generic and the "definition" is not populated - Expected: The Test Type should not be changed
