Fix wrong indent in internal client test

This results the unit test using 'wrong' storage policy configured
in swift.conf when lazy-loading the object ring, other than the one
specified in the with statment.

The reason why this test passes is get_object_ring uses ring index
as the parameter, so even with 'wrong' policy-0 name, internal_client
still can load the fakering with right index(0). But it will fail if
you specify policy-0 with ec_ndata + ec_nparity > 2
