[BUG] report output blending with previous config

[DumpySquare]

recently doing a demo and saw that the example config we previously reviewed was included in the report.

Need to make sure everything is cleared when the clear function is called

[DumpySquare]

pending fix in v1.8.0

updated the nsCfgViewProvider.clear() function to reset the diagnostics storage objects

    clear(): void {
        this.adc = undefined;
        this.explosion = undefined;
        this.parsedFileEvents.length = 0;

        // reset the diagnostic stats
        this.diagStats = {
            defaultRedirects: 0,
            Green: undefined,
            Information: undefined,
            Warning: undefined,
            Error: undefined,
        };
        this.diags = {
            defaultRedirects: [],
            Green: [],
            Information: [],
            Warning: [],
            Error: [],
        };
        this.refresh();
    }
