Saving document doesn't create new fields in existing collection

[bikash8gupta]

I have a collection which has few fields. I added new fields with some default values.
Now in order to query on those new fields, I tried iterating on whole collection and saving it so that the default values get stored in the db and can be queried. But it didn't create new fields in the database and hence cannot be queried. Earlier it used to work with older versions. Now I am using mongoengine 0.8.2
