Error when received more than one contact at same time

[iFernandoSousa]

When someone send me more than one contact at the same time, the code stop.
Debugging the code I saw that, when the message has more than one contact, the type of message is contact_array

This is the message when I receive just one contact:

I delete some pieces of message, because of the size, but it is a little bit to reproduce, just need to send more than one contact at the same time.
