Show errorSummary independent of suppressFailed

[dil-btarkovacs]

specReporter: {
            suppressSummary: true,
            suppressErrorSummary: false,
            suppressPassed: true,
            suppressFailed: true,
},

The above settings result in not showing any info about failing tests.
This means that currently there is no option to show the failed tests only as a summary.
As the format and the position of the summary are better, I think it would be good to have an option to show that only. This way, we could have the errors listed at the and of the log, with a nice format (numbered list), and without duplications.

I think because you suppress failed is set to true, which means not give failed test informations
