[PR #427/0a68bb27 backport][stable-2] CI is changed (#429)

* Is changed (#427)

* Refactor tests to use "is" and "is not" changed

* Refactor tests to use is succeeded or is failed

* Reformat indentation

* Add filter "bool" to prevent issues

(cherry picked from commit 0a68bb270f)

* Fix error message verification

I don't know why this works on main, but in stable-1, the error message
is "invalid privileges string: Invalid privileges specified:
frozenset({'INVALID'})"

* Add filter for test that won't work with mariadb

* Add test databases cleanup

* Backport small diff from main
