Error message on expect_column_values_to_be_unique Expectation on Teradata

[dsehnbru]

Describe the bug
Running validation on Teradata column against a expect_column_values_to_be_unique - Expectation resulting in error

To Reproduce

1. Create expect_column_values_to_be_unique - Expectation on any column of Teradata database
2. Run Expecation against Teradata datasource
   Expected behavior
   As this is obviously on of the most pivotal expectations, it should work against Teradata databases as well.

Environment (please complete the following information):

• Operating System: Windows 10
• Great Expectations Version: 0.13.44

Additional context
The expectation created in 1) works when run against a Sqlite database, so there has got to be a Teradata specific problem.

Hey @dsehnbru thanks so much for opening this up! Our support for Teradata is in the experimental phase so there may be some issues that we're not actively able to prioritize.

@imamolp recently did some work so tagging for visibility.
