Nothing is going to be planned out 100% of the way through, so just enjoy the ride. And that's not to dismiss the logical approach as to why Solo didn't believe in Jedi at the time...I think putting an in-world response is fun since it forces creative thinking...but I'm also not one to stress over it. Star Wars, as a whole, stands so tall that you can let a few little things like that slip through for the greater good.
