Subject: [PATCH] fix(member.unpack): fix payload position (#62)

Commit 7021e9f9209645d684b2cfcda9d63226cc1c7068 refactored
members.unpack function but introduced a typo with the position of the
payload in the array that forced payload to be ignored.

Such bug broke anti_entropy step, forcing incarnation to be updated
and payload to be ignored, making instances view of each other
inconsistent.

Closes #61
