Plot: handling of add_special and add_missing when show_bin_label is True

[ericlecoutre]

Hi

I observe a different behavior between

binning_table.plot(add_missing=False, add_special=False, show_bin_labels=False)

that removes correctlyt the two
options related to Special and Missing
and

binning_table.plot(add_missing=False, add_special=False, show_bin_labels=True)

That will strill display the two slots for Missing and Special.

I would find it more adequate to remove those ones.

I agree, that was not the intended behavior.
