> Decoding a message whose Properties/Symbol fields are read from a composite

> Steps to reproduce:
> 1. Build a ProtonCompositeBuffer out of at least two appended buffers where
> the first one is large enough that the second one does not start at
> absolute index 0 (e.g. 20 + 10 + 10 bytes).
> 2. Call copy(index, length, readOnly) with index/length fully contained in
> the second (or later) chunk.
> 3. Observe IndexOutOfBoundsException instead of the expected copied buffer.
