Move query logic into mongo (#1885)

* Move Parse Server logic into Parse Server and out of MongoAdapter

* Move untransforming up one level

* Make find() in MongoStorageAdapter

* Put nested object untransforming into it's own function

* Simplfy nested untransform

* Don't mess with inner object keys called _auth_data_*

* Prevent untransforming inner object keys named _p_*

* Fix inner keys named _rperm, _wperm

* Fix bugs with inner objects behaving strange when other fields have same name as key in specific circumstances

* remove params from untransform nested object

* Revert changes to find
