PHP 7.1.11
Using a function from trait ends up with using wrong function. 



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

trait traitA {
    public function __invoke() {
        echo "traitA\n";
    }
}


trait traitB {
    public function __invoke() {
        echo "traitB\n";
    }
}

class JustAClass
{
    use traitA {
        __invoke as protected hocus;
    }

    use traitB {
        __invoke as protected pocus;
    }

    public function __invoke()
    {
        $this->hocus();
        $this->pocus();
    }

}

$instance = new JustAClass();
$instance();

Expected result:
----------------
traitA
traitB

Actual result:
--------------
traitA
traitA
