PSA Hubspot trashes event properties

[nigelsim]

As much of a public service announcement as anything. If HubSpot is one of the analytics providers, it mutates the properties object it gets from the subscription to add its own additional properties. We need to clone the events before passing to _hsq.push

We send it this

{
  "event": "show",
  "properties": {
    "category": "screen",
    "label": "activity-stream",
    "screen": "activity-stream",
  }
}

And the object is this when its done

{
  "event": "show",
  "properties": {
    "a": 3997179,
    "b": "203733263.8.1742973083895",
