Component testing does not honour configuration values provided by plugins.

Current behavior

In Cypress ^6.8.0 it was possible to configure component testing using a plugin file by modifying the received configuration. Since the release of 7 this is no longer possible and requires you to configure component testing in the cypress.json file instead.

Desired behavior

It should honour the plugin overrides.

Test code to reproduce

The Cypress.json that is now required, (this was empty on 6.8.0)

{
  "component": {
    "componentFolder": ".",
    "fixturesFolder": false,
    "ignoreTestFiles": "**/node_modules/**",
    "testFiles": "**/*.cypress.js"
  }
}

The previous configuration merged in a plugin file:

module.exports = function (on, base) {
    const config = require('deepmerge')(base, {
        testFiles: '**/*.cypress.js',
        integrationFolder: 'cypress',
        ignoreTestFiles: '**/node_modules/**',
        experimentalComponentTesting: true,
    });

    return config;
}

Packages: -cypress: ^7.2.0 -@cypress/react: ^5.4.2 -@cypress/webpack-dev-server: ^1.1.6

Environment: -Node.js: v12.9.0 -NPM: 6.10.2
