Send all received WebSocket frames to app

Prior to this commit, if the WebSocket client received multiple
WebSocket frames in a single Erlang message by gen_tcp, the WebSocket
client sent only the first received WebSocket frame to the application.

This commit fixes this bug by having the WebSocket client send all
WebSocket frames to the application.
