Description:
------------
Reflection API returns lower case method name when multiple traits are nested.

Test script:
---------------
trait TraitA {
        function sameName() {}
}

trait TraitB {
        use TraitA {sameName as someOtherName;}   
        function sameName() {}   
}

class SomeClass {
        use TraitB {sameName as yetAnotherName;}   

        function sameName() {}   
}

$reflection = new \ReflectionClass(SomeClass::class);
var_dump($reflection->getMethod('someOtherName')->getName());

Expected result:
----------------
string(13) "someOtherName"

Actual result:
--------------
string(13) "someothername"
