Update route_controller.js

In order to ensure that streaming works in a server side route, we cannot call `this.response.end()` in the finally block as this is called regardless of whether there is an error or not. The below code will fail with large files (over ~800K) without this change:

    this.route("poster", {
		where: "server"
		, path: "/post"
		, action: function() {

			var _self = this;

			var _write = fs.createWriteStream("/tmp/test.tar");
			_self.request.pipe(_write);

			var size = 0;
			
			_self.request.on("data", function(data) {
		            size += data.length;
		            console.log('Got chunk2 ' + data.length + ' total: ' + size);
		  	});

		  	_self.request.on("end", function() {
		  		console.log("ALL DONE");
		  		_self.response.end("Thanks");
		  	});

		  	_self.request.on("error", function(e) {
		  		console.log("ERROR: " + e.message);
		  	});

		}
	});
