Cleaned up and fixed tests for CLI Org.

* Since organization labels cannot contain the same type of date that
  organization names can accept as values, I have modified the existing
  tests that require labels to be configured to use a limited set of
  values.
* Broke down tests that were getting skipped due to real bugs, Redmine
  and Bugzilla, and added new tests to specifically test these issues.
  The outcome is that those tests will now run and we will have target
  specific tests for the issues themselves.
* Updated assertions to be more specific instead of relying on
  assertTrue or assertFalse only. Now tests use assertEqual,
  assertNotEqual, assertIn and assertGreater.
* Found a nasty issue where certain organizations could not be listed by
  its label. Tests that encounter this issue will now fail instead of
  erroring out. See Bugzilla #1075239 for more information.
* Fixed the skip decorator for 2 tests where they were missing.
