"Save composition with a new name" button is enabled when composition has not been saved even once

Found issue:

• When creating a new effect, "Save current composition with a new name" button is enabled, even if user has not saved the composition even once yet.

Steps to reproduce:

• Create new empty project
• In Effect Composer, add some effect, e.g Rain
• "Save current composition with a new name" button is now enabled, even though composition has not been saved with any name yet
• Would expect only "Save current composition" button to be enabled
