fix(startup): make startup windows if there are only floating windows (#34349)

Problem:  If user init creates a floating window, startup windows
          (e.g. to accomodate arglist files) are no longer created.
Solution: Check that firstwin->w_next is not floating when deciding
          whether to make startup windows.
