Feature fix render new event type dashboard

[singhmi4]

What it Does

• when creating a new Event Type (Meeting Type) through an axios post request, addMeetingType function is called from UserProvider context and the new Event Type is passed in which updates the user state before redirecting to the Dashboard:

  const addMeetingTypes = (newMeetingType) => {
    setUser(prevUser => { 
      return {
        user: {
        // copies the previous user object
        ...prevUser.user, 
        // appends the newMeetingType created to the meetingTypes object
        meetingTypes: [...prevUser.user.meetingTypes, newMeetingType] 
      } 
    }});
  }

  What to Look For

• DRY code
• code review from #59 will be addressed here

What to Avoid

• 59 will not be merged in as this one includes all of the commits from that branch

• context performing the actions that would make more sense in a reducer

I think this would also close https://github.com/hatchways/team-vampire/pull/60 right?
