[IMP] pos*: improve tracking_number computation and payment method auto selected

pos*: point_of_sale, pos_self_order

In this PR, we improve the tracking_number computation decreasing the
number of string manipulation and increasing the number of int manipulation
in the backend. In the frontend, the computation of the tracking_number
was wrong. It was previously taking the whole session id and concatenate
it with the whole sequence number. We also fix that. It now takes the
last digit of the session id and the 2 last digits of the sequence number.
We also improve the payment_screen. Now, when the user arrives on the
payment_screen. If there is only 1 payment method. This payment_method
will be chose by default.

We also fix the display of the tracking number in the order reminder
page in pos_self_order.
