Subject: [PATCH 3/3] Fix runaway promise warning

Not returning any value in the promise chain resulted in a warning like
this:

(node:165) Warning: a promise was created in a handler at app/node_modules/telegram-bot-api/lib/telegram-bot.js:1680:13 but was not returned from it, see http://goo.gl/rRqMUw
    at new Promise (/app/node_modules/bluebird/js/release/promise.js:79:10)
