* Update babel-preset.js

As './dist/server/build/babel/preset' now return a function, in this example we need to first call the function and after that replace styled-jsx

* linting issues solved

Firebase server side auth example update: don't fetch messages server-side if user is not found (#3087)

* don't fetch messages server-side if user is not found 

Currently, the component always fetch everything under '/messages' even if the user is not authenticated on the server side. Update it to not fetch if the user is not found as a better example on handling.

* fix lint error
