[BUG] NullReferenceException when placing an SVGImage inside a DataGridCheckboxColumn

[lukas-kirschner]

Describe the bug
When I place an SVGImage inside a DataGridCheckboxColumn and change the DataContext, my program crashes with a System.NullReferenceException inside the OnSourceChanged method of the SVGImage.

To Reproduce
Steps to reproduce the behavior:

1. Create a User Control X with a Datagrid and a DataGridCheckboxColumn, place an SVGImage inside the DataGridCheckboxColumn and set its URI to a relative path that points to an existing SVG resource
2. Create a ContentPresenter inside a different UserControl
3. Programmatically change the Content of the ContentControl to different instances of the UserControl X

Expected behavior
The SVGImage is displayed correctly with its Source set to some existing URI, and invisible with the source set to Null or DependencyProperty.UnsetValue.

Additional context
The problem occurred with SVGImage 5.1.1 and .NET8

We have updated to 5.2.0 from Nuget but still seeing the issue. From what I can see on Github release 5.20 is still based on source from Dec 2023?
