[Tarantool-patches] [PATCH 01/17] recovery: do not call recovery_stop_local inside recovery_delete

[Cyrill Gorcunov <gorcunov@gmail.com>]

From: Georgy Kirichenko <georgy@tarantool.org>

Recovery stop local raises an exception in case of an recovery error
so it is not safe to stop recovery inside recovery delete and guard
inside local_recovery. So call recovery_stop_local manually.

Part of #980, #3794
