do not die when error in config parsing of buf occurs

If a config parsing error in a file occurs we can die and let the user fix the issue. This is different for the buf parsing function since it can be used to parse blobs of .gitmodules files. If a parsing error occurs here we should proceed since otherwise a database containing such an error in a single revision could be rendered unusable.
