[FIX] point_of_sale: localeCompare is not a function when name is false

When the loaded res.partner has `name` = false, the call to localeCompare
fails because boolean doesn't have the method. Note that `name` field
of res.partner can be false because no default is specified in its
declaration in the base module.

closes odoo/odoo#80501
