Fix issues with admin_scripts tests in regressiontests
There are 66 failing tests with the same reason for failure. They expect an empty stream and get errors about failed imports.
"AssertionError: Stream should be empty: actually contains 'b'Traceback (most recent call last):\r\n File "./manage.py", line 4, in <module>\r\n from . import settings # Assumed to be in the same directory.\r\nValueError: Attempted relative import in non-package\r\n''"
This issue is being handled by subgroup 3.
