Summary: [clang-tidy] clang-apply-replacements: Don't insert null entry Fix crash when running clang-apply-replacements on YML files which contain an invalid file path. Make sure we never add a nullptr into the map. The previous code started adding nullptr to the map after the first warnings via errs() has been emitted.
