Incorrect type for nullable morph

[matysekmichal]

Summary

Command php artisan ide-helper:models do not consider nullable morphs, and recognize such properties as \Illuminate\Database\Eloquent\Model|\Eloquent. Instead it should be of type \Illuminate\Database\Eloquent\Model|\Eloquent|null.

// migration

Schema::create('examples', function (Blueprint $table) {
    $table->nullableMorphs('column');
});

// class Example

public function column(): MorphTo
{
    return $this->morphTo('column');
}

Can you make a PR with tests?
