Add support for custom date class via Date::use() (#859)
Add support for custom date class via Date::use() (#859)

Laravel 5.8 introduced a feature to support a custom date class via
`Date::use()`, see https://github.com/laravel/framework/pull/25320

When e.g. using `Date::use(CarbonImmutable)` in a project, it means
all date casts are not returning `\Illuminate\Support\Carbon` anymore
but `\Carbon\CarbonImmutable`, which means all the generated type hints
for dates are now wrong.

This change tries to be still backwards compatible with Laravel < 5.8
which do not have the Date facade.
