In b7cc53e92c806b73e14b03f60c17b7c29e52b4a4 we port tag.c to use ref-filter APIs for filtering and printing refs. But that commit missed out on setting 'filter->with_commit_tag_algo' which would ensure the correct algorithm is used for the '--contains' option. As reported by Jerry Snitselaar, this causes the option to work way slower than expected, fix this by setting 'filter->with_commit_tag_algo' in tag.c before calling 'filter_refs()'.
