There is no feature to turn the skin before the walls. The skin layers are printed best after the walls. I would say that you might have some adhesion issues here.
I have to option in mind here: try some settings to make the adhesion for the first layer easier. Try a higher first line height (like 0.25mm) and an increased first layer with (like 120%). Print the first layer slow (20 or even 15mm/s). I kinda guess from experience that your nozzle is carrying the first printed hole line away?
Second idea: remove the bottom layers (by setting them to 0) and check infill before the walls. This way you might not have a 100% solid bottom layer, but the infill structures, so you achieve somehow what you want...
And increasing the "Initial Layer Flow" is another option. I agree with @Gero that it's an adhesion problem rather than an "order" problem. I print a lot of parts for assemblies and I use 2mm holes (and pieces of filament) to locate the parts at assembly. I haven't had a problem with PLA (on a clean bed) or with PETG (using hairspray to aid the adhesion).
