Title: [FIX] Unset "Use Company Address" when parent company is deleted.

Impacted versions:
7.0 and 8.0

Steps to reproduce:
1. Create a contact, associate with a company and set "Use Company Address"
2. Delete company which contact is associated with

Current behavior:
Unable to change contact's address fields because they are mark readonly

Expected behaviour:
Change address fields as usual
