[SPARK-24208][SQL] Fix attribute deduplication for FlatMapGroupsInPandas
A self-join on a dataset which contains a `FlatMapGroupsInPandas` fails
because of duplicate attributes. This happens because we are not dealing
with this specific case in our `dedupAttr` rules.
The PR fix the issue by adding the management of the specific case
added UT + manual tests
