Fix Wizard HIDs moved off by one

In commit b3f96d2c
I made a mistake that caused a lot of Wizard HIDS go off by one
i.e. they were attached to the next UI item.
I noticed this in the Fax wizard.
Adding one more empty array item seems to fix this.
Problem was caused by the replacement of this line with an empty item:
"", "HID:WIZARDS_HID_IS_BTN_NONE", # HID:41002
