Type inheritance is ignored when coercing object fields

[Alexander Tivelkov]

An Object field type coerces its values by comparing its obj_name() (if present) with the one required by contract.
This ignores object inheritance.

For example:

class Foo(base.VersionedObject):
    pass

class Bar(Foo):
    pass

foo = Foo()
bar = Bar()
field = fields.Field(fields.Object(obj_name="Foo"))
field.coerce(None, None, foo)
field.coerce(None, None, bar) # should pass, as bar is instance of Foo, but fails

This bug has been open for a long time, can anyone confirm that it's still present in the current version?
