[FIX] base: Individual contact gets Company icon
[FIX] base: Individual contact gets Company icon

Steps to reproduce:
- Create a contact (Company).
- Create a "child" in this company.
- Select "Contact" as type of address.
- Create an individual child of the company.

Bug: instead of having the Individual icon (Human being), it gets the
Company icon (Building).

Fix: the behavior must be the same as in 8.0, the avatar must be used
for a contact which is not a company.
