Removed spaces in the requests payload
Removed spaces in the requests payload

I removed the spaces before and after the array brackets because they don't allow partial matching in testing.

Instead of doing this:

```
stub_request(:post, /api.gosquared.com\/tracking\/v1\/event/).
          with(body: [hash_including({
              person_id: "email:#{user.email}",
            })]).
to_return(status: 200, body: "")
```

You need to do some hacky thing like this:

```
stub_request(:post, /api.gosquared.com\/tracking\/v1\/event/).
          with(body: "[ #{{
              person_id: "email:#{user.email}",
              event: {
                name: 'Some event that you might not want to test but you need to in order to have a valid mock',
                data: {
                  wtv_data: 'random data',
                },
              }
            }.to_json} ]").
to_return(status: 200, body: "")
```
