Archive by id or _id fails in MongoDb

Hello, I have detected that the "archive" method fails in MongoDb when you set the config property "schema" to true and try to do a "soft delete" for id or _id.

```
fn: async function (inputs, exits) {
// That line fails
await SharedDocument.archive({id: "5b0fae71d8785b29956bf65f"})

// That line fails too
await SharedDocument.archive({_id: "5b0fae71d8785b29956bf65f"})

return exits.success({ status: "Ok" });
}
```

With either of the two cases (id or _id) the following error occurs
```
Could not use the provided `where` clause. Could not filter by `_id`: `_id` is not a recognized attribute for this model (`shareddocument`). And since the model declares `schema: true`, this is not allowed.
```
Then, if you show the database, there are two copies of the record, one in SharedDocument, and other in archive, so I guess sails is failing to delete the original.
**This only happens if the model config parameter "schema" is set to true**

Thank you guys!

Start by reproducing the failure with SharedDocument.archive({id: ...}) and SharedDocument.archive({_id: ...}) while the model has schema: true, using the versions and Ubuntu environment listed in the issue. Inspect the archive path and MongoDB adapter behavior around the reported `_id` filtering error; done means both forms archive the record without leaving the original copy.
