Model configuration `schema` is not taken into account by the populate() query.

Hello,
I set my model config file with `schema: false` to prevent attributes filtering of the documents retrieved from mongo DB (for different reasons, the models in sails are not always defining all attributes of a document).
But the join document retrieved by a populate() query does not follow that `schema: false` configuration, and the attributes of the joined document **are** filtered according to the model.

For example, in database there are the two documents in different collections:

collection user: { _id: "a user ID", tenant: "a tenant ID", theme: "a theme ID" }
with a sails model like (this is not a real sails model but just an illustration): { id: { type: "string" }, tenant: { model: "Tenant" } }

collection tenant: { _id: "a tenant ID", lang: "fr", configuration: "A configuration" }
with a sails model like (this is not a real sails model but just an illustration): { id: { type: "string" }, configuration: {type: "string"}}

a query like: `sails.models.user.findOne({ id: "a user ID" }).populate('tenant')` returns a user document like:
{ id: "a user ID", theme: "a theme ID", tenant: { id: "a tenant ID", configuration: "A configuration" }}

The `lang` attribute of the tenant has been filtered out as it is not defined by the tenant model, but the `theme` attribute of the user has been preserved as expected.

Start by reproducing the reported sails-mongo case from the model configuration using schema: false and a user query with populate('tenant'). Trace how populate() retrieves and filters the joined document, then verify that the populated tenant preserves attributes not declared by its model while the issue's example user behavior remains unchanged.
