Removing tab from saved set

[ariutta]

I can't repro on demand, but here's a placeholder for a bug I've noticed multiple times in Tabli 0.9.3, Chrome 52.0.2743.116 (64-bit), OS/X 10.10.5. When I've tried removing (unchecking) a tab, let's call it TabD, from a saved set where TabD is not the top tab, Tabli removes the top tab in the saved set instead of TabD. If I move TabD to the top of the saved set, I can successfully uncheck it.
