Bugfix in newer versions of Unity

The removed line was not functioning as intended, it was covering the disclosure triangle of a parent GO with the mushroom icon if that parent GO also had a flowchart component.

I'm sure there was a reason for this logic change, so I've left the if cases intact, but this was necessary in my own project so I thought I'd share it.
