Saving composed effects doesn't work properly in non-default folder

• Make an effect with effect composer and save it
• Make a folder called "foobar" under project's content folder
• Move the effect into the "foobar" folder
• Clear the effect composer
• Doubleclick the effect in assets view to open it in effect composer
• Change some property of the effect to enable save button
• Save the effect

--> A new copy of the effect is created under default effects folder. The copy that was opened is unchanged.
