journal-remote: zero-initialize MHD daemon wrapper

MHDDaemonWrapper_free() unconditionally unrefs both event sources, but
setup_microhttpd_server() could return before initializing either pointer.
Zero-initialize the wrapper so cleanup after MHD startup failures safely
unrefs NULL.

Follow-up for 3c67c8bd4c5784bbcc644e489b9a39c0d2bc0e42
