Please review the test case in the patch. I have added tests for node translation only. Term translation tests are not yet done, I will soon add them, but the logic will be same as I have used for node testing.

Just to see that the test logic is fullproof, I have also attached a patch that includes only the test and not the code fixes, that patch should fail testing.

I am not removing "needs tests" tag because term testing is not yet done.
