[FIX] base: ignore context key in compute_display_name for res_partner

If you create a partner with a e.g. the key show_vat, it will be stored on
the partner while we would like to have this information only in the name_get.

After this commit, we will stop to save partner in our production database
with the vat number stored in the name because we create the partner (with vat)
from the invoice, where partner_id have a context with show_vat.
