'intl.accept_languages': 'de-DE', doesnt work with nightwatch version 2.2.1

[kmahata]

As part of internationalization we used to set browser locale using 'intl.accept_languages': 'de-dE', and worked fine with 1.7.12. Trying to upgrade and browser locale is no more set. Any help around it would be useful. Tried for different locales and nothing works. I can see in verbose it gets set properly as 'intl.accept_languages': 'de-de',
