Prevent PHPStan error: 'Uuid::fromString() on a separate line has no effect.'

[staabm]

Description

in a codebase which uses this lib like

<?php

require 'vendor/autoload.php';

function doFoo(string $id):void {
    try {
        \Ramsey\Uuid\Uuid::fromString($id);
    } catch (InvalidArgumentException) {
        throw new InvalidArgumentException('Invalid UUID string provided: ' . $id . '.');
    }
}

... and covers it with PHPStan, before this PR we ran into this error:

vendor/bin/phpstan analyze test.php --debug
Note: Using configuration file /Users/staabm/workspace/uuid/phpstan.neon.dist.
