Remove tile_extract from config when creating stats

[chrstnbwnkl]

Issue

When running valhalla_add_predicted_traffic using a config that has an entry for both mjolnir.tile_dir and mjolnir.tile_extract, the summary (if requested) will be created from the tar, not the tile directory. The predicted traffic is added to the tile directory though, so according to the summary, no speeds were added. This PR just removes the mjolnir.tile_extract before creating the summary, so it reads from the tile directory instead.
