Failing CI: geopandas + spaghetti

[jGaboardi]

The release of geopandas==0.13.0 is resulting in 58 failures with the following message:

AttributeError: You are calling a geospatial method on the GeoDataFrame, but the active geometry column to use has not been set. 
There are no existing columns with geometry data type. You can add a geometry column as the active geometry column with df.set_geometry.

These are ultimately tied back to spaghetti, whose main is passing, but needs a fresh release. Prior to that release, I would like to see pysal/spaghetti#721 and pysal/spaghetti#724 resolved.
