You cannot just disconnect the wire and have the input floating. If an input has nothing connected to it but is set for interrupt monitoring, it's just going to fire randomly based on electrical noise. This doesn't indicate a problem, it's just how electronics work.
Super basic electronics lesson: if you have an input on being monitored, it must have something connected to it. Connect the pin to earth and you'll see that everything is fine.
