[FIX] point_of_sale: reuse cashbox instead of always creating one

Version 9.0 comes with a revamped accounting system, and the
cashbox system for cash control on bank statements was changed in the
process.

The POS App was updated to use the new system, but failed to
reuse the existing cashbox control if one already existed.
This worked as expected on bank statements directly, but not
on POS sessions where a new cash control had to be input every time.

This fix requires an update of the views, but works in a
backwards compatible manner. Users who do not sync their view
definitions will still be able to work (but will still experience
the bug).
