[FIX] partner_firstname:

[legalsylvain]

overload missing 'private' partner form view (used in HR > employee > Private Information at least). add first and last names fields.

[zalei-odoo]

In res_partner.py you need
# Disabling SQL constraint givint a more explicit error using a Python
# contstraint
_check_name = models.Constraint(
"CHECK(1=1)",
"Contacts require a name."
)
Also Views have wrong xpaths
