PULSE managed to create a situation where machi_proxy_flu_client1 would appear to fail a remote attempt to write_projection. The client would retry, but the 1st attempt really did get through to the server. So, if we hit this case, we try to read the projection, and if it's exactly equal to what we tried to write, we consider the op a success. Ditto for write_chunk. Fix up eunit test to accomodate the change of semantics.
