Mocha helper does not end test on failed expectation

[Naktibalda]

INFO: Track my order failed: AssertionError: expected 'Hello. How can I help you?' to include 'Hello. How can I help you?2'
Unhandled rejection AssertionError: expect.fail()
    at testbuilder.setupTestSuite (E:\projects\botkit-starter-web\node_modules\testmybot\helper\mocha.js:16:21)
    at async.eachSeries (E:\projects\botkit-starter-web\node_modules\testmybot\lib\testbuilder.js:51:17)

This output is printed quickly, but the test keeps running until timeout.

This issue is mocha specific, jasmine handles assertionError correctly.
