[FIX] point_of_sale: Fix access point for IoT Box

When the box is in "access point" it calls the function 'get_wifi_essid'
at every ping => ~ 3 seconds.
So after a few moments the network card blocks and turns off.
Now we redirect the user to the '/steps' route that only executes the function once.

closes odoo/odoo#41415
