getThreadHistory.js ERR! getThreadHistoryGraphQL TypeError: Cannot read property 'id' of null

[diginatrium]

First of all, I'm sorry if this is the incorrect way to report it.

Based on https://github.com/Schmavery/facebook-chat-api/pull/661

I'd recommend making the following change:

line 374 of getThreadHistory.js could use a similar fix of:
packID: d.sticker.pack.id, to packID: d.sticker.pack != null ? d.sticker.pack.id : '',
otherwise "ERR! getThreadHistoryGraphQL TypeError: Cannot read property 'id' of null" gets thrown when getting a history of several chats.

The edit alleviated the problem at least for me.
