Parse `saveEventually` fails to save array of pointers after the record on the backend has been edited

1. Save a row with a field arrayOfPointers on iOS, with empty array of pointers.
2. Update another field on the row.
3. Try to update the arrayOfPointers with an actual pointer (let's call it somePointer), and save.
4. Observe that arrayOfPointers does not contain somePointer, as expected

When parse gets passed an array, we make a copy of that array, and store it, since #102. The behavior you were relying on was inconsistent and relied upon the implementation detail that parse wouldn't make copies of mutable arrays like most sane Cocoa/CocoaTouch APIs did.

@richardjrossiii So what do you suggest that I do?

Your logic should now look something like this:

NSMutableArray<PFObject *> *arrayOfPointers = [myObject.arrayOfPointers mutableCopy];
[arrayOfPointers addObject:myNewPointer];

myObject.arrayOfPointers = arrayOfPointers;
