Fix migration error

[richmahn]

Has migration issues from v1.4 to v1.8 (looks like skipping 1.7 is the problem, as 1.4 to 1.7 has no problems). Unless they fix it, this must be done before running gitea:

CREATE INDEX IDX_repository_is_bare ON repository (is_bare);

CREATE TABLE u2f_registration(idbigint(20) NOT NULL AUTO_INCREMENT,namevarchar(255) DEFAULT NULL,user_idbigint(20) DEFAULT NULL,rawblob,counterbigint(20) DEFAULT NULL,created_unixbigint(20) DEFAULT NULL,updated_unix bigint(20) DEFAULT NULL, PRIMARY KEY (id), KEY IDX_u2f_registration_created_unix (created_unix), KEY IDX_u2f_registration_updated_unix (updated_unix), KEY IDX_u2f_registration_user_id (user_id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;
