Subject: [PATCH] Removing unnecessary callback

I'm doing this in response to a compilation error on MSVC 2015.  As far as I can tell, this is a bug in the compiler.  My basis for asserting this is that placing the following declaration within the 'endpoint.on_open = <<lambda>>' gives the same compilation error:

	const std::function<void(void)> mycallback = [](void) {};

Whereas moving that logic outside of the 'endpoint.on_open = <<lambda>>' does not give an error.

Normally I don't like working around buggy compilers, but in this case the callback is supposed to be optional anyways.
