Partially revert "aeed49a Fix filament runout on optical filament sensors"

Browse Source 
Revert plan move to filament change position before enqued M600.
This was workaround to problem that restore_print_from_ram_and_continue() did 3s heating pause before resuming print. This problem will be fixed properly in restore_print_from_ram_and_continue() in next commit.

Save 166B of FLASH.
