built-in server: exit when docroot does not exist

When the server:run command is run with an invalid document root
directory (for example, when being in the app directory and not
changing the document root to ../web/), the command crashes on Windows
with a 267 exit code. On Linux, the server starts but just publishes
internal server errors.

[DependencyInjection] fixed missing 'factory-class' attribute in XmlDumper output

Symfony\Component\DependencyInjection\Dumper\XmlDumper didn't write 'factory-class' XML attribute for definitions on which setFactoryClass() was called.

This caused the Container[Builder] to throw an exception when the relevant service is being requested/initiated after loading the dumped XML:

`Uncaught Exception Symfony\Component\DependencyInjection\Exception\RuntimeException: "Cannot create service "xxx" from factory method without a factory service or factory class." at /<path>/<to>/vendor/symfony/dependency-injection/Symfony/Component/DependencyInjection/ContainerBuilder.php`

Fixed the problem, and updated the relevant test fixture.

Problem: XmlDumper doesn't write 'factory-class' XML attribute for definitions on which setFactoryClass() was called.

Impact: Container[Builder] to throws an exception when the relevant service is being requested/initiated after loading the dumped XML.
`Uncaught Exception Symfony\Component\DependencyInjection\Exception\RuntimeException: "Cannot create service "xxx" from factory method without a factory service or factory class." at /<path>/<to>//DependencyInjection/ContainerBuilder.php`

Solution: Made XmlDumper write the 'factory-class' attribute, and updated the relevant test fixture.

Another related problem, is that XMLFileLoader doesn't complain if the 'factory-class' attribute is missing for a 'service' elements that include 'factory-method' attribute, resulting in an ill-configured Definition object in the ContainerBuilder. I'll post an issue/ticket, and probably send another PR for that.

*BC note - this breaks code if people build on top of the incorrect returned value `drife`.

Fixes the `singular` for `drives`. I've added more test values to prove more edge cases and to show this changes doesn't break other `singular`-look ups.
In the test class i've added a few `known issues` for later reference/fixure.

Whilst using Mink to do automated tests, I encountered a problem where redirects with ports would not work as the port was removed in the `updateServerFromURI()` method. This PR fixes the problem.

During my testing I encountered `$client->followRedirects(false);` in the ClientTest class that was causing the redirectWithPort test to pass even though it should have been failing (Removing the line caused the test to correctly fail before the patch was written)

This fixes a problem I discovered today during Mink testing: I have a route with a slug and id, separated by colon (`/{slug}:{id}`). When the `HTTP_HOST` is being normalized it only checks for array key existence, not emptyness. In this case it was `false` due to the `parse_url` call in `updateServerFromUri`, which cannot handle this case:

```
$> php -r "var_dump(parse_url('/redirect', PHP_URL_HOST));"                                                                               NULL

$> php -r "var_dump(parse_url('/redirect:1234', PHP_URL_HOST));"                                                                          bool(false)
```

So now the url becomes `http:///redirect:1234`, because of the missing host.
