fix(Integrations): Stop overwriting HubSpot company names with Flagsmith org names

When a user signs up, the HubSpot integration overwrites the company
name with whatever the user typed as their Flagsmith org name. This
leads to incorrect names replacing real company names that HubSpot
already enriched from the email domain.

Now only sets the company name if HubSpot doesn't already have one,
using the email domain as a fallback instead of the org name.
