cypress-plugins: Problem with overriding mochawsome.json

Hi,

If we will run e.g "scripts": { "slack-report": "./node_modules/.bin/cypress-slack-reporter-full", }

Which have:

 mochawesomeReporterOptions: {
            reportDir: "cypress/reports/mocha",
            quiet: true,
            overwrite: true,
            html: false,
            json: true
        }

Overwrite is set to true, so if user will have more then one test the json file will be always overwritten, and we can’t merge couple of reports into one.

Could you check it?
