* Sending empty chunks by `writeChunk` should not release new
objects as this doesn't change `payloadSizeLimiter` internal
state.
* This also fixes the bug with patcher when an offset of a patch
equals to `MaxSize` - `payloadSizeLimiter` releases object again
although state is the same. This led to error because EC-encoder
receieved empty payload and couldn't not process it.
