Bug #48493 spl_autoload_unregister() removes all autoloaded methods when prepending

The spl_autoload_register function was recently modified (I don't think 
it's documented, though) to allow the pre-pending of functions to the 
stack (see bug #42823).

I'm using pre-pending and am later trying to remove a registered 
function from the end of the stack. This removes ALL methods, not just 
the method I'd intended.

Reproduce code:
function autoload1() {}

function autoload2() {}


// register autoload1 at the bottom of the stack
spl_autoload_register('autoload1', true, true);

// Output: Array ( [0] => autoload1 [1] => autoload2 )

// unregister autoload2 - autoload1 _should_ be left behind

Expected result:
When running spl_autoload_functions(), I'd expect a single entry to be 
left: array([0] => 'autoload1');

Actual result:
The array is empty: array();
