added unit test cases

I have added four unit test cases to get code coverage of 100% for this file:SoftLayer/CLI/account/events.py of these functions: test_account_events(), test_account_planned_events(), test_account_unplanned_events(), test_account_announcement_events() in /softlayer-python/tests/CLI/modules/account_tests.py
