Fix `fix` command to handle `--fixers` option when contains extra and excluding fixers

Currently, when `--fixers` option contains extra and excluding mixed filters such as `-eol_ending,concat_with_spaces`, excluding filter will be enabled, however, extra filter will not be enabled.

This PR fixes this behavior, so enable both type filters when mixed filters given.
