polish: put the AdvVP adverbial after the verb

AdvVP built its result with setPrefix, so the adverbial landed before the
verb. Polish is neutrally SVO, and this matters beyond adverbs proper: an
object reached through PrepNP arrives at AdvVP as an Adv, so a two-place
verb came out as *"π zbiór pusty przecina" rather than "π przecina zbiór
pusty". Both orders are grammatical, but the preverbal one topicalizes.

"śpi tutaj" is as good as "tutaj śpi", so the RGL's own example is
unaffected.
