Changes

Previously we filtered out users that were part of an organisation that had a paid subscription before sending them to hubspot. This PR removes that filtering.

How did you test this code?

I haven't, but it's just removing a few lines of trivial code which gets called in a single location.

Looks good, but we should have had test coverage for this.
