Run the Flow Rate Fine Pass on the Extruder the Coarse Pass Used

When the fine pass starts from the coarse page the filament comes from
the cached preset, but the extruder was resolved from whatever the
preset page currently has selected. After a restart or reconnect, or if
the selection was changed, that no longer matches and the lookup falls
back to the per-AMS map, which with a Filament Track Switch pins every
AMS to the main extruder. Take the extruder from the cache in that path;
it already records the one the coarse pass was sent with.
