Error when schema discriminators are used on embedded array fields

[catchshyam]

Hi,

One of my schema uses the discriminators as elaborated in this blog http://thecodebarbarian.com/mongoose-4.8-embedded-discriminators.html.

When I use such a schema with nest-mongoose, I get the following error,

....\node_modules@nestjs\mongoose\mongoose.utils.js:4
return ${JSON.stringify(model)}Model;
^
TypeError: Converting circular structure to JSON

I guess the code for generating model token will have to be changed since the schema JSON can not be serialized when there are discriminators.

Thanks.

The way to generate the token have to much problems I make PR to solve #4 but this solve this problem too.

Lets wait to @kamilmysliwiec to give us more info about this, beacuse the change had a break change.
