[lldb/crashlog] Fix test failure when creating a target using command options (#91653)

This should fix the various crashlog test failures on the bots:

```
  lldb-shell :: ScriptInterpreter/Python/Crashlog/app_specific_backtrace_crashlog.test
  lldb-shell :: ScriptInterpreter/Python/Crashlog/interactive_crashlog_json.test
  lldb-shell :: ScriptInterpreter/Python/Crashlog/interactive_crashlog_legacy.test
  lldb-shell :: ScriptInterpreter/Python/Crashlog/last_exception_backtrace_crashlog.test
  lldb-shell :: ScriptInterpreter/Python/Crashlog/skipped_status_interactive_crashlog.test
```

When we create a target by using the command option, we don't set it in
the crashlog object which later on cause us to fail loading the images.
