ISSUE:       2343
TITLE:       Better diagnostic when 'Missing security context'
DESCRIPTION:
    ::: NB :::
    List of AuthClient plugins must contain Win_Sspi in order to reproduce this test expected results.
    Otherwise firebird.log will not contain any message like "Available context(s): ..."
    Because of this, test marked as to be performed on WINDOWS only.
JIRA:        CORE-6362
FBTEST:      bugs.core_6362
NOTES:
    [20.06.2022] pzotov
        See also bugs/gh_7165_test.py
        Message about missed sec. context will raise if we make undefined ISC_* variables and try to connect.
        Confirmed missed info in FB 3.0.6.33301: firebird.log remains unchanged (though ISQL issues expected message).
        Checked on 4.0.1.2692, 3.0.8.33535.

    [13.12.2023] 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.
