Log exception when one of the tests fails

[waldekmastykarz]

When one of the tests in $ gulp test breaks at the end you get the following error:

/Users/usr/github/generator-office/gulpfile.js:129
  $.log(err.toString());
    ^
TypeError: undefined is not a function
    at Stream.handleError (/Users/usr/github/generator-office/gulpfile.js:129:5)
    at Stream.emit (events.js:129:20)

Shouldn't https://github.com/OfficeDev/generator-office/blob/master/gulpfile.js#L129 be referring to the function defined in https://github.com/OfficeDev/generator-office/blob/master/gulpfile.js#L113 (so calling log rather than $.log)?

This is an error, but it shouldn't call the local function log() because that writes out a successful message in blue all the time. It just needs to call the $.util.log() function instead.

Fixed in #85
