feat: start pasv port selection from last checked port (#111)

* Update find-port.js Reuse the Port Number Generator * feat(passive): initialize port factory in server Ensures that each passive connection does not have to start from the beginning of the pasv port range https://github.com/trs/ftp-srv/pull/110 * fix(connector): ensure data socket is destroyed and resolved If there was a data socket, this would never resolve * test: use bluebird promises for tests, fix stubs * fix(commands): ensure connector is ended before resuming
