Fix upgrade clause for mem3_rpc:load_checkpoint/4,5fix-upgrade-clause-in-mem3_rpc
When upgrading, the new mem3_rpc:load_checkpoint with a filter hash arg won't
be available on older nodes.
Filter hashes are not currently used anyway, so to avoid crashes on mixed
cluster call the older version without the filter hash part when the filter has
the default <<>> value.
