[10.x] Collection::except() with null returns all

[pniaps]

Similar to Collection::only() which allows null

framework/src/Illuminate/Collections/Collection.php

Lines 901 to 915 in c59d540

	public function only($keys)
	{
	if (is_null($keys)) {
	return new static($this->items);
	}
	if ($keys instanceof Enumerable) {
	$keys = $keys->all();
	}
	$keys = is_array($keys) ? $keys : func_get_args();
	return new static(Arr::only($this->items, $keys));
	}

this change allows to get all records, only or excepts the ones you want. For example, you can write

    public function get($only = null, $except = null)
    {
        return $this->connection->table($this->table)
            ->get()
            ->only($only)
            ->except($except)
            ->all();
    }

instead of

    public function get($only = null, $except = null)
    {
        $collection = $this->connection->table($this->table)
            ->get()
            ->only($only);

        if (!is_null($except)) {
            $collection = $collection->except($except);
        }
        return $collection->all();
    }

So I can quickly get all records of the table ->get();
only the records I want ->get([1,3,5]);
or all except some records ->get(null, [2,4]);
