Front room create not giving sufficient info to backend

[ebrakke]

We need to make sure to pass in the type of content to the backend.
Also, would should be using the keyword content as opposed to topic as this more accurately reflects the endpoint docs and the idea of a room.

Current we have this as the post statement for a room:
In Room.js (frontend/src/js/services)

$http.post(api, {
            title: room.title,
            topic: room.topic.content,
            lat: room.location.lat,
            lng: room.location.lng,
            radius: room.location.radius

Proposed change:

$http.post(api, {
            title: room.title,
            """ content """: room.topic.content,
            """ type: room.topic.type """,
            lat: room.location.lat,
            lng: room.location.lng,
            radius: room.location.radius
