WhatsApp pulse ratelimit hot fix

I had to discover that whatsapp quickly starts to block the status request overflow with an error message. The server only responses with the requested data again, when we stop our request for some itme.
Because of this, I dissabled the request of the statuses and the pulse will now just ask for the pictures. WhatsApp does not block these requests.

WhatsApp pulse rate limit hot fix
fix for my mistake

I'm sorry, I made a bad mistake and put the line which defines the contacts array also in the if block. Of course this breakes the images_ids reques since it receives a undefined array. >.< This fixes it, I tested it properly.
