Fix electric-pair-tests by disabling bug#33794's fix with a variable

The variable c--disable-fix-of-bug-33794, which should be removed in
the short term in favor of a permanent solution, is introduced.

It is bound to nil by default.  This means that breakage is still
happening in actual c-mode and c++-mode usage, though the tests no
longer show it.

To get around this breakage, put

   (setq c--disable-fix-of-bug-33794 t)

In your init file.  Evidently, you will lose the fix for bug#33794,
but that only affects a small corner case of c-toggle-auto-newline,
which is not turned on by default.
