Update make_summary for pandas-0.25 compatability.

Browse Source 
The pandas Index union operation does no longer produce a MultiIndex but a Index tuple in pandas-0.25.2.
This causes the script to fail. (The problem does not exist with pandas-0.24.0.)

Fix by explicitly checking for this case (only the first loop iteration).
