[tarantool-patches] [PATCH] sql: raise err on CHECK + ON CONFLICT REPLACE

[Ivan Koptelov]

Adds error raise in case of CHECK constraint declared with ON
CONFLICT REPLACE action. Before the patch such option was
forbidden, but if a user tried to create space with such constraint,
this attempt failed silently.

Closes #3345
