Incremental Model Fails When Column Varchar Size Increases (Edge Case)

[alittlesliceoftom]

When an incremental model's varchar size increases beyond the current default e.g. from VARCHAR(50) - (150) , dbt attempts to replace the column, however it makes syntax errors in SQL server:

Actual

ALTER TABLE database.schema.model
ADD COLUMN "Column__dbt_alter" CHARACTER VARYING(200);

Desired

ALTER TABLE database.schema.model
ADD "Column__dbt_alter" VARCHAR(200);

I may be able to add a MRE later.

Dbt 0.19.1
