Dependency injection is not applying for objects instances retrieved from fields of type "href"

[kanevbg]

Steps to reproduce

Create two classes. In the second add field with name "myFirstObject", of type "href" and configure it to allow object of the other class.

Create with each class one object in the backed. Lets say object of the first class will get ID 1 and class 2 will get object with ID 2. On object #2 put a href to Object #1.

Create custom class "MyCustomFirstClass" which will extend the first class created from the PIMCore Backend.

Setup DI in /website/config/di.php for the custom class to replace the first one.
And check out what happens with that:

Code example

$o2 = \Pimcore\Model\Object\MySecondClass::getById(2);
$o1 = $o2->getMyFirstObject();

var_dump(get_class($o1));
var_dump(get_class(\Pimcore::getDiContainer()->make(\Pimcore\Model\Object\MyFirstClass::class)));

### Expected behavior 
"MyCustomFirstClass"
"MyCustomFirstClass"

### Actual behavior  
"MyFirstClass"
"MyCustomFirstClass"

Sorry, not actually bug. It was a caching issue, arghh...

Yes, after you change the DI config you have to flush the cache :)
