[Bug] building UDFs should create my custom schema

[graciegoheen]

Is this a new bug in dbt-core?

• I believe this is a new bug in dbt-core
• I have searched the existing issues, and I could not find an existing issue for this bug

Current Behavior

i have a function with a custom schema defined:

functions:
  - name: is_positive_int
    description: My UDF that determines if a string represents a positive (+) integer
    config:
      schema: udf_schema
      volatility: deterministic        
    arguments:
      - name: a_string
        data_type: string 
        description: The string that I want to check if it's representing a positive integer (like "10") 
    returns: 
      data_type: integer 

when i go to build this, it says my custom schema does not exist:

Expected Behavior

dbt should automatically create this schema, like it does for models:

Which database adapter are you using with dbt?
