findOne is slow if collection transform is adding big fields

[namirsab]

Observed Behavior

After the latest release (2.30.2) I've realized one of my collections was performing much slower when finding documents ( from ms to 3-4 seconds). To fix it, I had to reduce the transform of the document to a simpler object.

Expected Behavior

Kadira does not make the app that slower when finding documents in the database.

Reproduce by

Create a transform that adds a big field to a collection.
Measure the time to find a document

I believe you are stringifying the document or something like this on every findOne, meaning that if the object is big enough, it will take a lot of time.

But this was not happening before the latest release, so I wonder if #144 is related
