aaa77ae5 - fix count argument of replace! (#25427)

fix count argument of replace! (#25427) `replace!` had one stack-overflow problem reported in #25384. Its fix #25386 made a method-overwrite, tentatively fixed in #25422. But `replace!` also didn't handle non-Int count arguments as expected (because there is no dispatch on keyword arguments). This fixes the root problem and adds tests for non-Int count.
