don't works with insertMany

[Hisham-TK]

insertMany method at mongoose like create many
this plugin has to inject it's middleware at insertMany pre-post to populate on createMany

This is a little trickier than expected because there's no way to get insertMany() options in post('insertMany') hooks with Mongoose. That's something we need to work on: the context for insertMany() hooks should be something that enables accessing the options.

As a workaround, we're adding a populate option for insertMany() to Mongoose. That will enable this plugin to access insertMany() options, and we'll have a fix for this within the next couple of days 👍
