Fixed a bug where "Mark for Add" files did not have their status updated after a full revert.

Steps to replicate:

• Add a new asset
• Mark the asset with Right-click -> Source Control -> Mark for Add
• Perform a full revert via Source Control -> Revert
• Notice that the status of the asset is not updated to reflect the revert.
