Custom scripts cannot change interfaces on devices created by itself in a branch

[GoepiGB]

Plugin Version

0.8.3

NetBox Version

v4.5.5 (docker image netboxcommunity/netbox:v4.5.5)

Python Version

3.12.3

Steps to Reproduce

0. Create a fresh NetBox install
1. Create a site
2. Create a device role with the name 'switch'
3. Create a device template with at least one interface
4. Add this script to NetBox: https://github.com/GoepiGB/netbox-branching-issue-496/blob/main/BranchingTest.py
5. Create a branch
6. Run the script; select the site and device template created before, committing the changes is not necessary

Expected Behavior

The device is created, and the interface is assigned a description successfully

Observed Behavior

The script fails with a validation error:

ValidationError: {'__all__': ["Cannot modify interface '1' because it has been deleted in the main branch. Sync with the main branch to update."]}

Running the script in the main branch works without error.
