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):
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,
  File "/usr/lib/python3/dist-packages/graph_tool/inference/",
line 503, in minimize_nested_blockmodel_dl
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:

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

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