Hey @DisruptiveMind , there seems to be a merge conflict now. Could you maybe fix this? Thanks.

[janpio]

Thanks @DisruptiveMind.

Tests are now failing because of

/Users/travis/build/apache/cordova-plugin-camera/src/windows/CameraProxy.js
  790:67  error  Strings must use singlequote  quotes
✖ 1 problem (1 error, 0 warnings)
  1 error, 0 warnings potentially fixable with the `--fix` option.

This doesn't make too much sense to me, especially as line 790 contains no quotes at all.

Can you maybe rebase on master? I hope this will go away with more recent test configuration. Thanks!

Closing and re-opening to trigger a new CI/test run with new PR merge.
