Currently, if you have Spanish POS installed and create a Cash In/Out,
you are met with an error.
Steps to reproduce
------------------
* install `l10n_es_pos`
* start a POS session
* click on the hamburger button in the top-right corner > Cash In/Out
* add any amount and confirm
You should be met with an error.
Fix
---
At first glance, the original condition:
```
partner?.id !== props.data.simplified_partner_id
```
and the revised condition:
```
partner && partner.id !== props.data.simplified_partner_id
```
might seem equivalent. However, they behave differently when `partner`
is `null` or `undefined`.
In the original condition, the optional chaining operator evaluates
to `undefined`, leading to the following `undefined !==
props.data.simplified_partner_id` (which is most likely true).
The revised condition will shorcircuit when `partner` is falsy, ensuring
that the code only executes when `partner` is a truthy object.
