NetBox version

v3.2.1

Python version

3.9

Steps to Reproduce

Create a Script with MultiObjectVar field
Set null_option='Any'

    env_aggregate = MultiObjectVar(
        label = "Aggregate",
        model = Aggregate,
        null_option = 'All',
        required = False,

Run the script through the 'manage runscript' without providing any data.

Expected Behavior

Script runs fine

Observed Behavior

A TypeError is raised in DynamicModelMultipleChoiceField.clean()

f6402a8b62/netbox/utilities/forms/fields/dynamic.py (L125-L140)

The 'clean(self , value) gets the the 'value' parameter as 'None', if no data is passed to the script.
The 'in value' fails, as "argument of type 'NoneType' is not iterable"
