if lua function returns empty table libtarantool's iterators segfault

I have part of code like this: https://github.com/mailru/tarantool/blob/master/client/tarantool/tc_print.c#L67

And I worte some tests for the code:

https://github.com/unera/dr-tarantool/blob/master/t/test-data/init.lua#L7

function test_return(...)
    return { ... }
end

if we call function 'test_return' with some arguments, the code works fine, but if function returns empty table, iterators will segfault.

A test that demonstrates the problem here: https://github.com/unera/dr-tarantool/blob/master/t/100-lua_segfault.t
Binary packet that was returned by tarantool can be found here: https://github.com/unera/dr-tarantool/raw/master/t/test-data/lua-return-empty-tuple-type_00022-code_000-ok.bin

tarantool returned package that has length = 28 bytes, code = 0

function 'tnt_reply' returned 0 for the package, and then tnt_iter* functions segfaulted.
