Allow to() & from() with Model

[Gummibeer]

Allow to put in an EloquentModel in the to() and from() methods.

protected function setEntityAction($from, $property)
    {
        // Check if has the entity as parameter
        // it should be the firstOne
        if ($this->hasEntity($from)) {
            $this->isString($from[0]);
            $this->isNumeric($from[1]);

            $this->setBuilderData("{$property}_type", $from[0]);
            $this->setBuilderData("{$property}_id", $from[1]);
        } elseif($from[0] instanceof Model) {
            $this->setBuilderData("{$property}_type", get_class($from[0]));
            $this->setBuilderData("{$property}_id", $from[0]->getKey());
        } else {
            $this->isNumeric($from[0]);
            $this->setBuilderData("{$property}_id", $from[0]);
        }
    }
