Fix cross_border_type DB schema upgrade

[jaywilliams]

Running magento setup:upgrade while upgrading from v1.5.13 to v2.2.4 created the following error message:

Module 'ClassyLlama_AvaTax':
Upgrading schema..
Column "cross_border_type" does not exist in table "avatax_cross_border_class".

This pull request fixes this by checking if the column cross_border_type exists prior to attempting to rename it. In my instance the cross_border_type_id column was already in the DB, so renaming was unnecessary.

Steps to reproduce:

1. Upgrade from v1.5.13 to v2.2.4, run php bin/magento setup:upgrade
2. Downgrade from v2.2.4 to v1.5.13, run php bin/magento setup:upgrade
3. Execute the following SQL to fix website for registered customers:

   UPDATE eav_attribute set
   source_model=null, frontend_input='text'
   WHERE attribute_code='override_importer_of_record';

4. Upgrade from v1.5.13 to v2.2.4, run php bin/magento setup:upgrade:

Expected result:
✔ The module should be upgraded

Actual result:
❌ We have error Column "cross_border_type" does not exist in table "avatax_cross_border_class".

---

Actual result with changes from this PR:
✔The module successfully upgraded, command php bin/magento setup:upgrade executed w/o errors

For what it's worth, I'm currently experiencing this issue after upgrading to 2.2.5 on Magento 2.4.3.

I applied this PR as a patch and the issue was resolved.
