compilation error on adapter.drop_schema: no attribute 'drop_schema'

[abronner]

Using dbt version 0.15.0 + bigquery, I've created the following macro:

{%- macro delete_dataset(dataset_id) -%}
    {%- do adapter.drop_schema(target.project, dataset_id) -%}
{%- endmacro -%}

I run it with the following command:

dbt run-operation delete_dataset --args "{dataset_id: my_dataset}"

I get the following error:

Running with dbt=0.15.0
Encountered an error while running operation: Compilation Error in macro delete_dataset
'dbt.context.runtime.DatabaseWrapper object' has no attribute 'drop_schema' 

dbt docs ref: https://docs.getdbt.com/docs/adapter#section-drop_schema

hey @abronner - thanks for the bug report! This is definitely a bug - we'll get it fixed for dbt v0.15.1
