Saving Widget Blueprints directly can put them in a bad state.

The fixup code for repairing Widget bindings in UE5 assumes that a compile occurs first. However, saving the asset does not cause a compilation to occur. When we reload the asset and open it in the editor, it doesn't apply its fixup since the version check thinks it's up to date.

1. Create a new project and a Widget Blueprint in 4.27's editor.
2. Add a progress bar.
3. Select the progress bar. Under the "Progress" section in the details panel, look for a dropdown next to "Percent" and select "Create Binding".
4. Compile the widget, save, and exit.
5. Open the same project in UE5.
6. Open the Widget Blueprint's editor.
7. Hit compile and observe error.
