Internal exceptions aren't surfaced

[tipa]

I have hit a case in which a WebDAV server doesn't respond with a valid XML or error code when sending a PROPFIND request, but with an HTML page (and response code 200). When trying to parse the HTML, an exception is thrown in XDocument.Parse. But this exception is caught and awaiting the Propfind method doesn't throw the exception.

WebDavClient/src/WebDav.Client/Helpers/XDocumentExt.cs

Lines 7 to 17 in 20d4523

	public static XDocument TryParse(string text)
	{
	try
	{
	return XDocument.Parse(text);
	}
	catch
	{
	return null;
	}
	}

From the PROPFIND response it is not apparent if the server responded with an (invalid) HTML, or with a (valid) empty PROPFIND response
