Update for deeply nested cfs-file's broken

[petermikitsh]

The experimental update image functionality seems to work, but only if the property is defined at the document root. Nested properties raise errors.

Example:

AutoForm declaration:

{{ #autoForm collection='MyCollection' doc=myDoc id='myForm' type='update' }}
    {{ >afQuickField name="deeply.nested.imageId" type="cfs-file" collection='images' }}
    <button type="submit" class="btn btn-primary">Update</button>
{{ /autoForm }}

It seems to be an issue with the deepDelete function called in cfs-autoforms-hooks.js:

Call Stack:
