[BUGFIX] Adapt ObjectConverter test with new symfony/property-info

With symfony property-info 7.1.2, the type resolving for
collections has been hardened.

https://github.com/symfony/property-info/commit/d0bbc495f11ab99a1e2cbf04699331b88b3c1293

Our extbase ObjectConverter test for collections uses an anonymous
class with an ObjectStorage property. The annotation for the property
as well as the native property type is however not a FQCN. So the
anonymous class has no information about, what FQCN the
`ObjectStorage` class is.

The change adds the FQCN for the ObjectStorage in the
anonymous class, which resolves the failing test, and
adds a test with a non-anymous class to test short
namespaces still work.
