`filter_emission()` returns duplicate rows #17

While working on #16, casting to IamDataFrame raised an error that filter_emission() in the first test returns duplicate rows on the index "AT - CO2 - 2026" and "AT - CO2 - 2027".

This was intentional, as the filter steps were not initially returning aggregated values.
