[FIX] pos_restaurant: stay on current table after refund

Previously, when conducting a refund on a table, the system would
switch the active table to the table associated with the refunded
order. This was not the desired behavior, as it resulted in the details
of the order disappearing, requiring the user to navigate back to
the refund process.

Steps to reproduce the issue:

 - install PoS restaurant
 - pick a table, do an order and pay it
 - pick another table, refund
 - choose the previous order and refund
-> the order details disappear directly. You have to go back to refund.
