[tarantool-patches] [PATCH] sql: remove meaningless triggerE test

[Nikita Pettik <korablev@tarantool.org>]

Originally, SQLite doesn't allow to use binding parameters in trigger's
body. triggerE test checks only this taboo. However, binding mechanism is
not properly implemented now, so this test seems to be useless and can
be removed.
