Fix `core.redraw` when window is not focused (#1601) 

* Execute at least one step when window has no focus

This way if `core.redraw` is set, it's respected.

* Fully run threads at least once when window has no focus

This allows threads that set `core.redraw` (like `projectsearch`) to 
continue running even after the window loses focus.

"Fully" here means that `run_threads` has gone through *all* the "timed 
out" coroutines at least once.
