clearToken exception is thrown at wrong place.

The PR https://github.com/symfony/symfony/pull/8528 has added a problem when logger is enabled.

The log message for clearToken exception throw actually a fatal error because $failed doesn't exist in clearToken method. I have moved the log message to the handle method.

This PR solves issue with tests in the SecurityBundle: current structure of tests force to repeat the same test case for every format (PHP, XML, YAML) even if it doesn't depend on them (see #8782).
