Modification of collections of linked objects.

[tmarzec]

Because inner objects don't have their objectKeys assigned, any update on a non-empty collection of objects sends over back an inner object, which cannot be then found in the database.

Reproduction

Consider schemas:

{
    name: 'apple',
    properties: {
        name: 'string'
    }
}
{
    name: 'basket',
    properties: {
        content: 'apple[]'
    }
}

Lets say that we have two apples, a and b, and let basket c be:

{
    content: [a]
}

If we now add b to c.content from the UI, then an error will happen on the device.

Solution

Ideally, this would be fixed after resolving #85 and #84, when proper object flattening and type conversions are in place.
