The box.tuple.new() used to call luamp_encode_tuple with
default LUA serializer config &amp;#39;luaL_msgpack_default&amp;#39;. This
routine may consider an array to be excessively sparse when
  + encode_sparse_ratio &amp;gt; 0
  + max(table) &amp;gt; encode_sparse_safe
  + max(table) &amp;gt; count(table) * encode_sparse_ratio.
Sparse optimization save memory via representing excessively
sparse tuple as MP_MAP. But Tarantool tuple always must be
MP_ARRAY so it is not relevant for box.tuple.new semantics.
So it is disabled with encode_sparse_ratio = 0 in a new local
serializer config.

Closes #3882
