Error in plot_isi_histogram for default cutoff value

[JuliaSprenger]

For viziphant version 0.1.0 the usage of the default parameters for the plot_isi_histogram results in

'numpy.float64' object has no attribute 'rescale'

Here is a minimal breaking example

st = neo.SpikeTrain([1,2,3]*pq.s,t_stop=10*pq.s)
viziphant.statistics.plot_isi_histogram(spiketrains)

Thanks, your script actually spot two bugs in ISI plotting ;)

Don't know how to test viziphant other than calling the functions all possible ways to check that no error is triggered.
Currently, I test the doc tests only. But it'll become an issue quickly if viziphant starts growing.
