[Foldit] Fix logic bug for GUI toggle.
As part of PR #5733 I added a convenience function to re-enable the GUI elements if you clicked on the menu button.
This was only supposed to be active if you had the GUI hide enabled, but I messed up the logic a bit, and turned the main icon into a general GUI Hide toggle. This should fix it.
