[Mac] Restore the Chrome main menu if there are no windows on the active space.

When an app window closes, we skip restoring the Chrome main menu if
there are other windows to minimize the number of times the main menu is
changed. This doesn't work if the other windows are on different spaces.
This ensures the Chrome menu is restored if there are no other windows
on the active space.
