I got this message in one application (CLI):

```

  [InvalidArgumentException]
  Invalid locale: en_US .

```

It's not so easy to spot the issue.

properly handle null data when denormalizing

If null is passed to denormalize(), no property values can be set on
the denormalized object. Additionally, this fixes passing values to
the denormalized object's constructor if the incoming data is an object.

server:run command: provide more error information

The server:run command didn't provide many information when the executed command exited unexpectedly. Now, the process' exit code is passed through and an error message is displayed.

This is, for example, useful, if you provide an invalid ip address/hostname on which the server couldn't listen.
