[PhpUnitBridge] Fix class_alias() for PHPUnit\Framework\Error\Error

PHPUnit 6.x removed the PHPUnit_Framework_* classes in favor of PHP namespaces, but one error class did not map the same as the others: `PHPUnit_Framework_Error`.

Instead of mapping to `PHPUnit\Framework\Error` in the same way that `PHPUnit_Framework_Error_Warning` mapped to `PHPUnit\Framework\Error\Warning`, this base class was replaced with `PHPUnit\Framework\Error\Error`.
