HTTP/3: fixed parsing encoder insertions with empty header value. When starting processing a new encoder instruction, the header state is not memzero'ed because generally it's burdensome. If the header value is empty, this resulted in inserting a stale value left from the previous instruction. Based on a patch by Zhiyong Sun.
