* BUG: Fixes asset writer to the select the latest asset to hold a sid

When constructing the asset_info dataframe, we were previously taking
the first symbol/sid pair to include, when we should be taking the most
recent.

* Ensure groups are sorted by increasing end_date

* Updates test_lookup_symbol_change_ticker to also cover asset_name
