Parse references in quotes

[theofidry]

It seems that this has been added to support the switch to '@ref' for the YAML parser but it actually shouldn't be needed. To be checked and see if this feature should be deprecated in 2.x or not.

public function testLoadParsesReferencesInQuotes()
    {
        $res = $this->loadData([
            self::USER => [
                'user1' => [
                    'username' => 'alice',
                ],
            ],
            self::GROUP => [
                'a' => [
                    'members' => ['\'@user1\'']
                ],
            ],
        ]);
        /** @var Group $group */
        $group = $res['a'];

        $this->assertInstanceOf(self::USER, current($group->getMembers()));
        $this->assertEquals('alice', current($group->getMembers())->username);
    }
