Description:
------------
When using namespaced classes as a type hint like in the test script attached to this bug report, the ReflectionParameter object generated for the parameter contains a fully-qualified class name for the type hinted class where the name of the namespace is duplicated (see actual output).

This also causes ReflectionParameter::getClass() to fail as no ReflectionClass object can be created for the invalid class name.

Test script:
---------------
<?php
namespace ImageTransform;

interface FileAccessAdapter
{
  public function create(ImageTransform\Image $image, $width, $height);
}

$method = new \ReflectionMethod('ImageTransform\FileAccessAdapter', 'create');

foreach ($method->getParameters() as $parameter) {
    print $parameter;
}
?>

Expected result:
----------------
Parameter #0 [ <required> ImageTransform\Image $image ]Parameter #1 [ <required> $width ]Parameter #2 [ <required> $height ]

Actual result:
--------------
Parameter #0 [ <required> ImageTransform\ImageTransform\Image $image ]Parameter #1 [ <required> $width ]Parameter #2 [ <required> $height ]
