Missing issue count in the header of the config review panel

The issue was found by @marcin during 1.12 sanity checks.

The config review component has a broken summary text:

It starts with "issues found in...". The totalIssues value that should be output before this text is undefined, so it is not visible here. It creates an impression that some issues have been found, but in fact it should say: "No issues" (so the opposite).
