Subject: [PATCH] Ensure that `Dict_getArray` doesn't fail if `xref` in
 undefined (PR 6485 follow-up)

In PR 6485 I somehow missed to account for the case where `xref` is undefined. Since a dictonary can be initialized without providing a reference to an `xref` instance, `Dict_getArray` can thus fail without this added check.
