Specifying multiple child filters shows them comma separated in the request

I'll need to reconfirm this, but filing the issue so I don't forget. I recall that when doing a listCalendarObject call with various filters, I saw many commas in the actual http request. It seems that the server I'm using is ignoring them, but it is not quite correct.

Yah, and this breaks test='anyof' for caldav on Baikal. Why are these simple patches not accepted...
