Prevent element-wise string comparison

Browse Source 
Issue #835 shows that comparing `bins`, which may be a numpy array, with a string `'auto'` leads to element-wise comparison, because the `==` operator for numpy arrays is used. With this commit, potential array and string are switched, so the `==` operator for strings is used, which does no element-wise comparison.
