inference.minimize_nested_blockmodel_dl does not support bs != None

I'm running the current version. If I try to provide a list of np.arrays that
contain the hirarchies, I get the following error:

Traceback (most recent call last):
  File
"/usr/local/lib/python3.5/dist-packages/IPython/core/interactiveshell.py",
line 2847, in run_code
    exec(code_obj, self.user_global_ns, self.user_ns)
  File "<ipython-input-104-5c3124f01cab>", line 2, in <module>
    gs[i], deg_corr=True, bs=asd,

line 503, in minimize_nested_blockmodel_dl
    base_type=type(min_state),
UnboundLocalError: local variable 'min_state' referenced before assignment

Basically, min_states is only defined if bs is None, in which case
get_states() gets called. As soon as one provides bs, that breaks down.

The reason I report this bug here is that I get the following error whenever
I try to click on git or issues on the web:

Misdirected Request

The client needs a new connection for this request as the requested host
name does not match the Server Name Indication (SNI) in use for this
connection.

This is an incompatibility problem with older browsers; it has been fixed
now. You can also go directly to git.skewed.de.

Please open an issue there, and it will be dealt with.

(Remember to provide a simple, self-contained example that shows the problem.)

Best,
Tiago
