use class method when calling Runner::get_default_cfg

Summary:
Pull Request resolved: https://github.com/facebookresearch/d2go/pull/404

`get_default_cfg` is now class method since stack of D37294926 (https://github.com/facebookresearch/d2go/commit/b077a2c13845d4ef8481979d64345368864fe5ff), this diff updates call sites using biggrep to replace "Runner().get_default_cfg" with "Runner.get_default_cfg"
