[Tarantool-patches] [PATCH v1 10/12] test: put require in proper places

["Alexander V. Tikhonov" <avtikhon@tarantool.org>]

From: Sergei Voronezhskii <sergw@tarantool.org>

* put `require('fiber')` after each switch server command, because
  sometimes got 'fiber' not defined error
* use `require('fio')` after `require('test_run').new()`, because
  sometimes got 'fio' not defined error

Part of #2436, #3232

(cherry picked from commit d2f28afaf7f045687df191cd93c935dcc442811b)
