--drop-existing doesn't work with dbt seed

[jthandy]

when attempting to recreate tables that had previously been built with dbt seed, an error message shows saying that the table already exists.

This can happen if there's a view with the same name as the csv file. Do you think that's what's happening here @jthandy? The --drop-existing flag logic looks like correct otherwise.

totally possible, i'm not sure.

--drop-existing is now deprecated, use --full-refresh instead.

We overhauled dbt's implementation of seed -- This particular error is handled by alerting the user that they're running a seed file with the same name as a view in the database.
