Title: Changes getKernel to be a static function

`MinkTestCase::getKernel` should be a static function as `WebTestCase::createKernel` is. The whole chain to get the kernel should be static as it's dealing with a static member of the class.
Otherwise calling `getKernel` from a static environment requires to use error suppression to suppress the warnings.
