Fix blaze websocket server example

See original GitHub issue

If I run the websocket server example for blaze from the examples-blaze sub-project

runMain com.example.http4s.blaze.BlazeWebSocketExample

and point the websocket.org echo client at it, it fails during connection with the following error:

[NIO1SocketServerChannelFactory] INFO  o.h.blaze.channel.ServerChannelGroup - Connection to /0:0:0:0:0:0:0:1:59297 accepted at Tue Jun 23 13:29:03 PDT 2015.
[info] 13:29:04.286 [pool-1-thread-1] INFO  org.http4s.blaze.pipeline.Stage - Unknown connection header: 'Upgrade'. Closing connection upon completion.

For control, I spun up a sample Unfiltered websocket server and did the same thing, and it worked as expected.

I think one of the difficulties I had is that I am testing a client impl at the same time. The moral here is to use a known-good client test tool and debug only one side at a time! 🙄

👍 I was just looking at the code and trying it without and it works. Thanks for testing!
