Fix pre- and post-command-hook errors in term.el

Before this patch, after the terminal process dies the command
hooks added in term-mode's char mode would produce errors.
This fix removes these hooks when the process dies.
* lisp/term.el (term-handle-exit): Remove pre-command-hook and
post-command-hook because the process is dead.  (Bug#31236)
