Can't map object to abstract|interface with AsObjectMapper

[Norbytus]

I try manually map object to interface impl, with AsObjectMapper, but always get error
Trying to instantiate "TargetInterface", but it is not instantiable. You might solve this problem by adding an "InheritanceMap" to the class, so the mapper will know which concrete class to instantiate.

It's then you try SourceInterface class map to certain class like

final readonly class Mapper
{
    public function map(SourceInterface $source): Target
    {
        /*....*/
     }
}

But get error on opposite direction

final readonly class Mapper
{
    public function map(Source $source): TargetInterface
    {
        /*....*/
     }
}

The bug is there, and should be fixed by the related PR. However, I got a different error message here. Try clearing your cache, and try again, my guess you will now get "Target class ... is not a valid class". If correct, then we have a cache invalidation bug that should be fixed for dev environment.
