Change React version of examples to latest

[juanbzpy]

I changed the version to the following files:

• - examples/with-next-css/package.json
• - examples/with-draft-js/package.json
• - examples/custom-server-polka/package.json
• - examples/with-cerebral/package.json
• - examples/with-zones/package.json
• - examples/with-universal-configuration-runtime/package.json
• - examples/with-apollo/package.json
• - examples/with-higher-order-component/package.json
• - examples/with-hashed-statics/package.json
• - examples/with-pkg/package.json
• - examples/with-jest/package.json
• - examples/with-glamorous/package.json
• - examples/with-custom-reverse-proxy/package.json
• - examples/with-emotion/package.json
• - examples/with-styled-jsx-scss/package.json
• - examples/with-styled-jsx-plugins/package.json

with-emotion/package.json already has the latest, so I guess it's other packabe. BUT I think we need to update this example with the latest version of emotion since it changed a little bit (for better).
