/**
 * `Migration20200101046150_a_ski_tour_keeps_its_piste_router_options` gives a
 * tour one more column, `ski_options`: the JSON text of the piste router's
 * options and the build its legs ran on. Every tour that was there keeps its
 * columns and reads NULL in the new one; the column takes the server's JSON.
 * A tour kept in a collection gets the same column.
