Print files: a transient failure to load the places table is retried on the next print

Browse source 
loadPlaces memoised an empty table on ANY failure, so one network error meant no
city dots for the rest of the session, while the other pinned loaders retry. A
table that is not served (or a reader offline) is now forgotten, so a later print
tries again; wrong bytes, refused after the fresh refetch, stay refused for the
session.
