`narrowType` doesn't work with `get()`

[mordechaim]

Suppose I want to narrow a type but return in get:

db.book.find(1).get('name').narrowType()<number>()

the type is ignored:

This doesn't work either:

db.book.find(1).narrowType()<{ name: number }>().get('name')

I could just use as number, but the get could also be part of a subquery.

I published a fix:

// 1st is supported now:
db.book.find(1).get('name').narrowType()<number>()

// 2nd is not supported,`get` isn't aware of previously narrowed types:
db.book.find(1).narrowType()<{ name: number }>().get('name')
