[Tarantool-patches] [PATCH v3 1/2] test: cleanup tests code

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

Cleaned up the tests code according to the Lua style guide:
- made scoped variables local
- added os.exit call at the end of the test chunk
- adjusted the messages in test:ok calls

Part of #4655
