[Tarantool-patches] [PATCH 1/2] tuple: fix non-informative update() error message

Fri Jan 10 10:28:25 MSK 2020
Calling tuple_object:update() with invalid argument number
yields 'Unknown UPDATE operation' error. Instead, we replace this
error with explicit "wrong argument number", mentioning which operation
failed, or poiniting out at invalid operation code.
Fixes #3884
