live stills: rugnux integrates every frame, whatever the broker's quick_integration

JFJochReceiverRugnuxStills::AnalysisSettings started from the broker's
spot-finding settings, and IndexAndRefine gates integration on their
quick_integration - whose API default is false. With the default, live stills
integrated nothing and merged nothing. The analysis settings now switch
integration on themselves; JFJochReceiverRugnux_Stills runs with the broker's
default and failed before (no merge, no space group).
