[Stephen Girard] Incorrect alter table statement on Snowflake

[drewbanin]

Issue

Issue description

The 0.13.0-a2 release of dbt has a regression which causes Snowflake alter table statements to be built incorrectly.

Previously:

alter table db.schema.table__dbt_tmp rename to db.schema.table

In 0.13.0-a2:

alter table db.schema.table__dbt_tmp rename to table

As such, Snowflake tables/views defined to be built in custom schemas will instead be built in the target database/schema defined in the user's profile. Downstream models that select from these models will not find the relation, as it was built into a different schema than the one specified.

System information

The output of dbt --version:

0.13.0-a2

EDIT: This didn't appear to be an 0.13.0 alpha regression, and instead has lived inside of dbt for quite some time! Fixed in 0.13.0
