[BUG] expect_column_values_to_be_of_type is not able to test properly

[CarMoreno]

Is this a new bug in dbt-expectations?

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

Current Behavior

I am trying to test a few columns using expect_column_values_to_be_of_type, once I set the properties.yml file I get a weird syntax error:

Database Error in test dbt_expectations_expect_column_values_to_be_of_type_valid_chemical_data_mass__numeric (models/chebi_ontology/properties.yml)
  syntax error at or near ")"
  LINE 10:     ),

I was trying to run the SQL output from dbt_expectations and I got the same error. This is the content of the properties.yml file:

  - name: valid_chemical_data
    columns:
      - name: id
        data_tests:
          - unique
          - not_null
      - name: compound_id
        data_tests:
          - unique
          - not_null
      - name: mass
        data_tests:
          - dbt_expectations.expect_column_values_to_be_of_type:
              column_type: numeric #this does not work!

Dbt model is materialized as a Materalized view but I think it does not matter..
