[IN-69] Create User and POST to back-end when user logins

User Story

[IN-69] Nice

Changes made

TLDR: Logging in from either Landing or Login page makes call to back-end

• Cleaned up Profile page to reference data from state object
• Updated UserSchema to include authId
• Logging in with Google from the Landing page calls POST request to the back-end to make a new User object and uses the result from the request to update the redux state with the new User object
• Logging in with Google from the SignIn page calls GET request to the back-end to retrieve the User object from the db and uses the result from the request to update the redux state
• Logging in with email from the Landing page calls POST request to the back-end to make a new User object and uses the result from the request to update the redux state with the new User object
• Logging in with email from the SignIn page calls GET request to the back-end to retrieve the User object from the db and uses the result from the request to update the redux state
• Fixed GET User reducers and back-end resolvers
• Fixed POST User reducers and back-end resolvers

Does your new code introduce new warnings on dev console?

No
