In scope of tarantool/tarantool#8147, a new context-dependent extension for box tuples, MP_TUPLE, is introduced. If the merger's buffer source is used, raw MsgPack is received, which does not allow for passing the context required for decoding MP_TUPLE.
At the same time, all box tuples are now encoded as MP_TUPLE by default. If the merger's tuple chunk can be decoded by manually skipping the extension header of MP_TUPLE and the tuple format of individual tuples, the cursor is decoded using the Lua msgpack library, which cannot handle MP_TUPLEs without a decoding context.
The cursor's after_tuple field is a box tuple, so in order to overcome the limitation above, we need to explicitly convert it to a Lua table.
