cleanup: remove unnecessary cursor movement (#5)

We used to do the `stopinsert` synchronously before closing the window,
but it effectively didn't leave insert mode until after the window was
closed (and that caused some apparent cursor movement). Now that we're
deferring the window close action, we can remove the hacky cursor
respositioning.
