Change in README.md file

Hey Thomas! An awesome project indeed.

You might want to check point no. 5 in the .md file.

socketio chat connection string in client/src/components/chat/chatcontainer must be changed to the url that backend is running on, it is currently set to ?token=${token} for production so it needs to be set to http://localhost:8000?token=${token} for use in a local environment

Instead of 'client/src/components/chatcontainer' it should be 'client/src/pages/chat/Chat'
