Conditionally add PUSH_CERTIFICATES change option

If the server config reports that signed pushes are enabled, then we
need to add the PUSH_CERTIFICATES bit to our change detail request
options. This change will fetch the server config (if it's not already
pending or resolved) and wait for it to resolve before sending the
change detail request.
