Description:
------------
The extract() method of the RarEntry class does not to accept the password (3rd) argument, though the method seems to have it whenever I reflect the class.

I do know I can also provide the password using the RarArchive::open() method, but that is not relevant to this bug imho.

Take note: the protected test archive just contains a file 'txt.txt' having random textual content

Reproduce code:
---------------
$rc = new ReflectionClass('RarEntry');
$i=0;
foreach ($rc->getMethod('extract')->getParameters() as $p) echo "prm#".($i++)." {$p->name}\n";

$arc = RarArchive::open('protarch.rar');
$ok=$arc->getEntry('txt.txt')->extract(false,'C:\\tmp\\pwd_txt.txt', 'pass');
if ($ok) echo 'EXTRACTED';

Expected result:
----------------
prm#0 path
prm#1 filename
prm#2 password
EXTRACTED

Actual result:
--------------
prm#0 path
prm#1 filename
prm#2 password
