[FIX] web: BasicModel: default_get on o2m with date field

Before this rev., a crash occured when a default_get returned a
command 0 (CREATE) for a one2many, with a value for a date(time)
field (e.g. [0, false, {some_date_field: '2018-12-08'}]). This
was because the related values (inside the commands) weren't
parsed. This only impacted date and datetime fields, for which the
parsing converts the string into a moment instance.

Fixes #23672
