ID 239103 - Gizmos carry across object metadata which causes issues later on

Problem summary
If you create a series of nodes to use as a 'template' with an object with less patches, than the intended target object, the patch metadata is carried across and on export you will find that not all of your patches are exported.

Customer reported version

3.0v3

Customer reported platform
Linux

Steps to reproduce

1) Create a new Mari project with say 5 UDIMs

2) Create a basic channel in the nodegraph (I have attached one to this issue for ease)

3) Export the nodes as a gizmo

3) Create a new project with a series of UDIMs greater than the 'Template' project

4) Import the nodes, attach a paint node and put some arbitrary texture down

5) Export the channel as flattened and observe that not all the UDIMs are exported

Workaround
Create your 'Template' Gizmo with a series of UDIMs greater than whatever your target import project has.

Expected behaviour
