Python unittest do not run from Mantid script window

[abuts]

This issue was originally TRAC 10703

If one places a standard python unittest into Mantid script window and tries to run it, the script seems to do something, but no unit tests are run.

It seems, some system variables necessary for unittest to identify its tests are not set properly from Mantid Python window.

e.g., copying a unit test script below ant trying to run it reports:

---

Ran 0 tests in 0.000s

OK

while running it from IDE or python directly gives you as it should:

---

.........

---

Ran 9 tests in 0.091s

OK

Sample unit test script (any should do):
