autoGenerate: false doesn't work properly

Lots of finicky little bugs.

6cedcbc7a3f92bf2d3c94e5967fda14b8256e4ff was an example of a fix... that also caused others

Each time you change the behavior, verify that screenshotting works as expected. (Shouldn't that be a test :-[ )

Used to be tracked in #10.

• [ ] Bug: When screenshotting and autoGenerate = false, the run statuses update backwards
• [ ] Bug: The run status doesn't show the first run's result until the second run is generated, so it goes from all being gray to both popping in at once

Maybe just make it so autoGenerate is on by default? Flip it to onDemand or something?
