test(usage): disabled node then cached jobs counts 0 (#90, #347)

A PromptManager node with Save to library off records no cached-run
receipt and is no run prompt in the replayed job's graph, so ComfyUI
serving it from its cache on later jobs counts nothing. The prompt is
saved first by an enabled run, so a replayed count would show. Covers
PromptManager, Focused, Split, Text and the Pair.
