DAV\Client: Request body missing on PROPFIND after HEAD request

[evert]

Moved from https://github.com/fruux/sabre-dav/issues/649

When using the Sabre\DAV\Client to do a HEAD request, followed by a PROPFIND request, the latter fails because of a missing response body.

Reason for this problem is that the curl settings (including the CURLOPT_NOBODY option) are not cleared/reset between requests.

Test case:

<?php
require 'vendor/autoload.php';
use Sabre\DAV;

$client = new Sabre\DAV\Client(
    array(
        'userName' => 'admin',
        'password' => 'admin',
        'baseUri'  => 'http://wolke.bogo/remote.php/webdav/'
    )
);
//check if file exists
$client->request('HEAD', 'Notes');
//then fetch properties
$res = $client->propFind('Notes', array('{DAV:}resourcetype'), 1);
var_dump($res);
?>

Result:

PHP Fatal error:  Uncaught exception 'InvalidArgumentException' with message
 'The body passed to parseMultiStatus could not be parsed. Is it really xml?'

This happens with sabre/dav 2.1.3.

Needs to be fixed in the 3.0 branch of this project.
