Following commit 983c7e8152.
`_compute_display_name` is overridden in partner to force `show_adress` and some
other context variables to None. When those values are in the context, calling
`display_name` can give a different result than calling `name_get()[0][1]`.
This commit reverts the changes of the mentioned commit where the behavior is
actually different, that is, when `show_address` is in the context.
It also adds a comment on the `_compute_display_name` method to avoid further
mistakes.
