cleanup resource in setUpClass if ecxeption raised

this catch the exception in setUpClass of test_list_image_filters
and cleanup resource. Every exception should be catched
so hasn't specify what kind of exception after except.
In BaseComputeTest.create_server if a exception raised in
wait_for_server_status, the server won't be append to cls.servers
and cann't be deleted in clear_server.So change the order.
