FIX: deleteObjectLinked() element value matching add_object_linked()

CommonObject::add_object_linked() uses CommonObject::getElementType() to set element type in db. So should CommonObject::deleteObjectLinked(), or we might not delete previously created links

Can you describe how to reproduce the bug from screen ?
If you can't from screen, PR must be pushed into develop as it means it is a code quality enhancement.

I wouldn’t say code quality enhancement, but it wouldn’t show in Dolibarr screen either.
I’ll try and describe the use case.
I have a module in custom named module, with an object in it. I use $object->add_object_link() in, let’s say, an order.
In table llx_element_element, I will have

sourcetype => module_object, targettype => commande

If I delete my object, or call deleteObjectLink() for some reason, as $element is object and not module_object, the entry in element_element will stay there, causing unwanted (and potentially misleading) information to rot in the database.
This PR corrects that.
So this is not QUAL, imo, this is FIX!

Does it make sense for you, @eldy ?

As this affect only external module, this can't be categorized as a bug of dolibarr, but as an enhancement to allow a use case provided by external modules that is not yet possible. So you must push it into develop.
