Removed Model can cause dashboard to crash

[arthanson]

Deployment Type

Self-hosted

NetBox Version

v4.0.7

Python Version

3.10

Steps to Reproduce

Create a widget to a model (potentially plugin) on the dashboard
remove the model

In my case it was through development and having a widget to an object in a future PR.

Expected Behavior

The dashboard should still appear but the widget should not be rendered

Observed Behavior

NetBox crashes:

    return widget.render(request)
