After turning off paredit-mode, can't type unbalanced curly brace }

## Expected behavior

Turn on paredit-mode, then turn it off, and be able to type unbalanced characters `()[]{}`.

## Actual behavior

Can't type an unbalanced `}`

## Steps to reproduce the problem

Open a clojure file, run `M-x paredit-mode`, then run it again to turn it off. Try to type a `}`. Something of paredit mode persists and prevents it.
