Cython inline seems to be broken for new style classes

[rsaim]

In [18]: cython.__version__
Out[18]: '0.29.5'

In [19]: class Bar(object): pass

In [20]: code = "Bar"

In [21]: cython.inline(code, language_level=2)
...
TypeError: descriptor 'mro' of 'type' object needs an argument

This is basically trying to do query mro on type(<class>) which used to work for old style classes:

py3:

In [24]: type(Bar).mro()
...
TypeError: descriptor 'mro' of 'type' object needs an argument

py2:

In [74]: class Foo: pass

In [75]: type(Foo).mro()
Out[75]: [classobj, object]
