Date editor inside hasMany is broken

[eugenem]

Admin/models.php: AdminFormElement::hasMany( 'catering_dates', [ AdminFormElement::date( 'date', 'Date' ), AdminFormElement::text( 'details', 'Details' ), ]),

config/sleeping_owl.php 'dateFormat' => 'd.m.Y',

2 issues:

1. When you add a new row at this section, the date picker is not initialized
2. When you save the existing date (say 1.03.2021), it crashes due to incorrect date format (checked code, and at hasMany save handler you don't account for date format)

Workaround: changed dateFormat to 'Y-m-d'

I checked dev-development, it behaves the same way...

I will gladly accept PR for consideration) Alas, I don’t deal with this functionality, maybe later.

use ->setPickerFormat('d-m-Y')
