Wrong SequelizeDbAdapter constructor argument type

There is an issue with `moleculer-db-adapter-sequelize` [index.d.ts](https://github.com/moleculerjs/moleculer-db/blob/master/packages/moleculer-db-adapter-sequelize/index.d.ts#L30). Based on [source file](https://github.com/moleculerjs/moleculer-db/blob/master/packages/moleculer-db-adapter-sequelize/src/index.js#L24), there is missing `...` behind `opts` in types file.
