Make sure the deduplication of testcases and test results works in two directions.

[Sebastiaan127001]

For the metric named 'test cases' Jira is being used as a source for test cases.
JUnit, TestNG, and Robot Framework are supported as source for the test results.

test cases (Jira)	test results (JUnit)
test case 1	test result 1: passed
test case 2	test result 2: failed
test case 3	test result 3: skipped
NULL	test result 4:passed
test case 5	test result 5: untested
test case 6	test result 6: errored
test case 7	test result 7

The above table could be a realistic scenario. It would be great if the user can control what he/she can see and that he understands how this metric comes to the resulting measurement, in other words in which direction deduplication works.
I would like to be able to configure:

• all test cases that have no test result
• all test results that have no corresponding test case (orphans)
• and of course filter on all possible statuses

PS: errored is not a grammatically correct verb in English. Please use 'generated error', or just 'error'.
