Adjusts index type check warnings

[skrawcz]

Following #243 we need to adjust the warning
to make sense. Since we are not in danger of things breaking imminently. So the warning is just there for the user now to indicate how Pandas might be resolving indexes to create the dataframe.

Changes

• adjusts logger warning message to now match behavior after PandasDataFrameResult: Convert non-list values to single row frame #243 .

How I tested this

• locally.

Notes

@ianhoffman I think this should do the trick.
