Merge pull request #1 from revolunet/master

This is incomplete logic and makes the statement it wraps partially moot: ```(currentSlides || newValue)``` will never execute the ```newValue``` statement. Either this if statement should be changed to: ```if (currentSlides || newValue) {```, which is likely what you intended or the inner statement should be changed to: ```currentSlides.slice()```.
