Tests don't run for deduplicate macro

[dbeatty10]

Describe the bug

This is one instance within #558

The deduplicate macro is untested because this code refers to test_dedupe rather than test_deduplicate:

  - name: test_dedupe
    tests:
      - dbt_utils.equality:
          compare_model: ref('data_deduplicate_expected')

Steps to reproduce

cd integration_tests
dbt build --select +test_dedupe

or

cd integration_tests
dbt build --select +test_deduplicate

Expected results

The relevant test would run.

Actual results

Neither example runs the relevant test.

For the first example, it gives this warning:

01:40:33  [WARNING]: Test 'test.dbt_utils_integration_tests.dbt_utils_equality_test_dedupe_ref_data_deduplicate_expected_.2275e15126' (models/sql/schema.yml) depends on a node named 'test_dedupe' which was not found
