[PATCH v8 15/29] merge-recursive: make !o->detect_rename codepath more obvious

Previously, if !o->detect_rename then get_renames() would return an empty string_list, and then process_renames() would have nothing to iterate over. It seems more straightforward to simply avoid calling either function in that case.
