Fixed bug to support fields that are loaded by ajax. Classic example is paragraph bundle. Once field is added to paragraph bundle and later on added as reference field to content type this paragraph bundle is loaded by ajax on node add/edit form by clicking "Add new paragraph". Since svg_icon_field field is generated by ajax and it uses ajax by itself it needs to be handled differently.
Ajax callback element has changed. Discovered something like "#array_parents" :)
