Revisions do not work correctly on the code editor

1. All revisions are marked as saved (green) in the beginning.
2. Changes are not marked as saved after the effect is saved (They remain red).

Test:

• Open effect composer
• Add a random node
• Select advance mode
• Open code editor
• => All of the lines are marked as saved (green)
• Make a change in the code
• Save the effect
• => The change is still marked as unsaved (red)
