driver.close does not call the provided callback

[ornoone]

a difference between your driver and others is that no callback is ever caller after all migrations is applied:

DBMigrate.getInstance(true,{})
    .sync()
    .then(() =>console.log('migration done'))
    .catch((err) => console.log('migration failed', err))

will never have his then or catch called

I found that the source of this problem is that you never call the provided callback during driver.close(cb);

this callback is responsible for terminating the promise of all operations. (see db-migrate/lib/commands/on-complete.js:11)

do you still maintains this repository, and if so, would you merge a PR that fix this bug if I fill one ?
