[issue31506] Improve the error message logic for object_new & object_init

[Nick Coghlan]

Nick Coghlan added the comment:

Fortunately, the logic is already well encapsulated: there's a "if (excess_args && (case A || case B)) {... report error ...}" check at the start of each of object_new and object_init, where "case A" = "the other function in the object_new/object_init pair has *not* been overriden" and "case B" is "this function *has* been overridden".

That means the only change needed is to include the type name in an updated error message in case A, while retaining the current error messages for case B.
