bug#33840: electric-pair-mode breaks self-insert-command

[Alan Mackenzie]

Hello, Emacs.

In the master branch, put the following into *scratch* and evaluate it:

    (defun s-i-c ()
      (interactive)
      (self-insert-command 1))
    (local-set-key "(" 's-i-c))

On typing "(", it will be seen that the self-insert-command does its
job, correctly entering "(" into *scratch*.

Now do M-x electric-pair-mode.

If you now type "(", self-insert-command wrongly enters "()" into the
buffer.  This is a bug, and is the root cause of bug #33794.
