twister: test: update test case

update test cases for twister
1. test_errors.py add protection.
2. test_handlers.py change call to status
3. test_testsuite.py change call to status

The log traces for TwisterException objects only.
And the stack trace output follow the same rules for all exceptions,
but StatusAttributeError with its dedicated handlers.
