#2847

What's this PR do?

• Adds the VAT ID property in HubSpot properties sync command
• Fixes sync issues with choice group order

How should this be manually tested?

• Setup a test account on HubSpot
• Add a private app in integrations (settings->Integrations->Private Apps)
• Copy the access token secret and place it as a value for MITOL_HUBSPOT_API_PRIVATE_TOKEN
• Copy the client secret and place it as a value for HUBSPOT_PIPELINE_ID
• I would suggest reproducing this issue on master first:
  • Run ./manage.py configure_hubspot_properties once above configs are done
  • Notice error about duplicate orders in field choices of deal
  • Create a new user and also notice that you see 400 errors from sync_contact_with_hubspot
• Shift to this branch, And run ./manage.py configure_hubspot_properties again an this should succeed now
• Now manually trigger sync_contact_with_hubspot(<user_id>) and this should succeed
• Check that you see this user in Contacts on HubSpot
• Check that the user represents the VAT ID correctly on Hubspot contact properties

If you have any confusion, Please ping me.

Where should the reviewer start?

Setup a test HubSpot account - We can use xpro-dev account too but I would recommend setting up your own.

Any background context you want to provide?

We recently added VAT Id feat #2764 but this wasn't synced with hubspot
