Fixed an issue where branch companies couldn't compute taxes using AvaTax because they were looking for their own credentials instead of the parent company's. Now branch companies will automatically use the parent company's AvaTax credentials, since tax reporting is handled at the parent level. This eliminates configuration errors when setting up AvaTax for multi-company structures.

Create Branch
Set up Avatax on main company
Try to compute taxes using Avatax on Branch company
Issue: Receive error asking to add Avatax Credentials

When working with branches, Avatax should only be configured on the
main company and not from the branches, since the tax report will be
done from the parent.
