Hubspot user form call conflicts with hubspot api call under certain conditions

[mbertrand]

Steps to Reproduce

• Register a new user in xpro with email fake_user1@gmail.com
• A hubspot contact is created with that email
• Manually add a second email, fake_user2@gmail.com, to that same hubspot contact
• Register another new user in xpro with email fake_user2@gmail.com

Expected Behavior

The second email is removed from the 1st hubspot contact and added as a new contact.
The first xpro user is associated w/the first hubspot contact, the second xpro user is associated w/the second contact.

Current Behavior

The first email is removed from the 1st hubspot contact, the 2nd email becomes the primary email, and no new contact is created.
The first xpro user is no longer associated with a hubspot contact, the second user is associated with the 1st contact.

Possible Solution

The form seems to no longer be necessary. So as a first step, remove the value for it, and remove the error log statement that is triggered if it is null.
It may also be a good idea to sync the contact w/hubspot after every login as part of the auth pipeline to ensure everything is up to date.
A separate tech debt issue will be created to remove the form-related code altogether after we are confident that it is no longer necessary.
