Fixing master build on Travis (#1126)

* Use Travis sauce connect addon to connect to Sauce Labs

* Set Windows 7 as platform for testing IE11 on Sauce Labs

* Use ALLOW_SAUCELABS env variable to control Sauce Labs availability

* Run karma sauce tests only once in case of multiple node versions being used on Travis
