Inspector: layout panel doesn't reflect the correct layout

[EzioDCL]

Describe the bug
When opening a previously created scene that uses a custom layout, the Scene Layout panel information is incorrect. It often ignores deactivated single tiles or shows a different layout size.
Some examples:

• A 3 parcel "L" shaped layout shows as a 1x2 parcel layout
• Single deactivated tiles appear activated.

See attached images for more details.

To Reproduce

1. Create a new Empty Scene
2. Change the layout settings to 2x2 and deactivate one parcel so you end up with an "L" shaped layout
3. Apply changes and go back to the My Scenes screen
4. Open the previously created scene
5. Open the Layout Panel
6. Notice that the current Layout configuration is incorrect
7. This also applies to bigger and more complex custom layouts

Expected behavior
Layout panel preview should always reflect the current applied scene configuration
