Currently getting a collection from db.coll returns the same instance every time but calling db.getCollection("coll") will return a new instance every time. We should get these playing together.

these return the same instance

> var a = db.coll
> var b = db.coll
> a === b
true

these return new instances every time

> var a = db.getCollection('coll')
> var b = db.getCollection('coll')
> a === b
false
