Fix NIOHTTP1Server handleJustWrite always using response status "ok" (#…

…755)

Motivation:

Addressing the #713

Modifications:

Forward the statusCode from NIOHTTP1Server main handleJustWrite to ctx.writeAndFlush instead of always using "ok"

Result:

ChannelHandlerContext will write the correct status code even when it's not "ok"
