JS Warning About Not Enough Slides

I have generated MR, Kindly check it.
No Warning after that.

Please check it (:

Thanks. I thought it was safer to do make this logic in PHP, so I placed a few lines of code in the module to not even initialize swiper but do inform (status warning) user about it.
Note that this is only in 1.0.x-dev version for now. For 2.0.x will come soonest
