Unable to set vhost with amqp DSN

[rpanfili]

Hello there, I got some troubles using a DSN string to configure my connection to rabbitMQ with the default %2f vhost name

Expected Behavior

<?php
include('vendor/autoload.php');
use Enqueue\AmqpTools\ConnectionConfig;

$dsn = "amqp://guest:guest@localhost:5672/%2f";
$config = (new ConnectionConfig($dsn))->parse();

var_dump($config->getVhost()); // string(1) "/"

Actual Behavior

<?php
include('vendor/autoload.php');
use Enqueue\AmqpTools\ConnectionConfig;

$dsn = "amqp://guest:guest@localhost:5672/%2f";
$config = (new ConnectionConfig($dsn))->parse();

var_dump($config->getVhost()); // string(0) ""

Steps to Reproduce the Problem

1. composer require enqueue/enqueue enqueue/amqp-lib
2. execute the given piece of code

Version:

sw	vers
enqueue/amqp-lib	0.9.2
enqueue/amqp-tools	0.9.2
enqueue/dsn	0.9.2
enqueue/enqueue	0.9.3
enqueue/null	0.9.2
PHP	7.2.12

I think the problem is here:

enqueue-dev/pkg/amqp-tools/ConnectionConfig.php

Line 405 in 8b94d3a

'vhost' => null !== $dsn->getPath() ? ltrim($dsn->getPath(), '/') : null,

Since the given vhost is %f the path is urldecoded to // and the ltrim command remove everything, leaving an empty string.

I tried to patch (with success) like this:

'vhost' => null !== ($path = $dsn->getPath()) ?
                (0 === strpos($path, '/') ? substr($path, 1) : $path)
                : null,

Is there anything I'm missing about this kind of configuration?

That's a bug, only the first / has to be removed. Could you work on a fix?
