MDEV-23769: MTR can abort before it prints the test result summarybb-10.1-anel-MDEV-23679-mtrabort-v2

- Patch is solving generating report on warning
    To repeat the error run single worker:
    ```
    ./mtr --mysqld=--lock-wait-timeout=-xx 1st 1st --force --parallel 1
    ```
    or `N` workers with `N+1` tests with failures and `force`
    ```
    ./mtr --mysqld=--lock-wait-timeout=-xx 1st 1st grant5 --force --parallel 2
    ```
- Patch is doing cosmetic fix of `current_test` log file which holds the old log value of test `CURRENT TEST:..` in `mark_log()` in case of `unknown option` and as such
  the logic which is using it's content doesn't output valid log content and doesn't generate valid `$test->{'comment'}` message.asdf
