webdav3.exceptions.MethodNotSupported about webdav-client-python-3

[Ed1ks]

The reason for this error is:

    def parse_is_dir_response(content, path, hostname):
        """Parses of response content XML from WebDAV server and extract an information about resource.

        :param content: the XML content of HTTP response from WebDAV server.
        :param path: the path to resource.
        :param hostname: the server hostname.
        :return: True in case the remote resource is directory and False otherwise.
        """
        response = WebDavXmlUtils.extract_response_for_path(content=content, path=path, hostname=hostname)
        resource_type = response.find(".//{DAV:}resourcetype")
        if resource_type is None:
            raise MethodNotSupported(name="is_dir", server=hostname)
        dir_type = resource_type.find("{DAV:}collection")

        return True if dir_type is not None else False

it requires 'resourcetype' and 'collection' in xml, which dont exists.
If you download something with download_sync() it makes 3 times is_dir checks with requests:

1. download_sync()
2. download()
3. download_file()

This is broken and needs to be fixed!
