chore(travis): don't overwrite SauceLab config from Karma

The Karma config detects Travis and sets `startConnect` to `false`, but
this overwrite in Grunt was putting it back to the default of `true`.
This is probably why Travis is failing with connection issues, as it
tries to create a connection when it’s already open.
