Description:
------------
Directly created object ReflectionMethod returns wrong method name when method is aliased. As opposite, ReflectionClass::getMethod() returns correct name.

It affects PHP since 5.4

Test script:
---------------
<?php

trait A
{
	function foo()
	{
	}
}

class C
{
	use A {
		A::foo as alias;
	}
}

$rm = new ReflectionMethod('C', 'alias');
echo $rm->name; // returns 'foo'
echo "\n";
echo (new ReflectionClass('C'))->getMethod('alias')->name; // returns 'alias'


Expected result:
----------------
Should return 'alias' in the both cases.
