Refactor: Remove Login and Register Context

[rcamach7]

Why?

• These are defined as context at the top level of the app that will:
  • cause re renders anytime a form input changes when user is logging in / registering
  • cause performance issues due to large amounts of input changes that cause re renders
• Encapsulate the sign in and sign up functionality into their respective form components

How?

• Login and Register components should track their own input via states defined in that same component
  • create handler functions that update this state when input changes
  • on submission, make sure that these new states and their values are being used instead of the old context
  • remove all imports and lines related to old files
• Delete LoginContext and RegisterContext files
  • Delete all imports from these files wherever they exist
  • Delete these contexts from App.js file
• Update ResponsiveAppBar component
  • Right now it uses the isLoggedIn value from the LoginContext. Use UserContext instead and check for the truthly value of user to check if user is logged in / exists.
• Search for additional usages of these contexts and make appropriate updates (feel free to ask questions)
