Put a big sign "you must reload this page before any stats are displayed" somewhere on the web interface

Description of issue / feature request

On http://localhost:8089 I see start / stop buttons, and they work. But apart from that, nothing happens. RPS stays 0. The cmdline says number of locusts hatched. But that is is. I can click around on the tabs. They all show blank graphs / stats. I am getting confused. I try different locustfiles. Same behaviour. I try literal examples from the docs. Same stuff. Nothing happens on the web interface. I seriously start to doubt myself. I spend an hour of two getting more frustrated. How is it possible that no one else seems to have similar issues?

Then I see the remark somewhere "Note: There is no persistence of these charts, if you refresh this page, new charts will be created". Maybe I should reload the page. I do so. And wonder of all wonders: stats start appearing and graphs starts to be plotted.

Expected behavior

After pressing start, graphs and stats start being updated. Or there is a big sign saying: "you need to press reload if you want to see something happen".

Actual behavior

nothing happens in the web interface. everything stays at 0 / blank.

Steps to reproduce (for bug reports)

start from scratch with a new--possibly somewhat broken---locustfile, that you then try to fix.
