[Tarantool-patches] [PATCH 08/14] box/txn: move setup of transaction start time to txn_prepare

[Cyrill Gorcunov <gorcunov@gmail.com>]

It is more logical to put this timestamp in prepare
state. Also this will allow us to reuse the txn_prepare
code.

Note the former code did the same -- this member get
set right after txn_prepare call so nothing changed.
