[Tarantool-patches] [PATCH v5 4/8] refactoring: set diagnostics if sequence_by_id fails

[Ilya Kosarev <i.kosarev@tarantool.org>]

In refactoring: use non _xc version of functions in triggers
(b75d5f85338158eb1734ca8832d3c4b8ac0b4086) sequence_cache_find was
replaced by sequence_by_id. It led to the loss of diagnostics in case
of sequence_by_id failure. Now it is fixed.

Part of #4247
