ISSUE:       5132
TITLE:       Grant update(c) on t to U01 with grant option: user U01 will not be able to `revoke update(c) on t from <user | role>` if this `U01` do some DML before revoke
DESCRIPTION:
JIRA:        CORE-4836
FBTEST:      bugs.core_4836
NOTES:
    [12.12.2023] pzotov
    Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
    ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
    Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
