Title: Let me newgle that for you...

Support uninitialized collection navigation properties

Issues #451, #152

Specifically:
- Collection can be null for Contains and Remove calls
- Collection is initialized if possible if null when Add is called. Same rules used for the type to instantiate as in EF6.
- Error checking for when we can't use/initialize the collection
