Deleted this file since we are testing already for conversation entity import with test_generic_data_types

[Gabefire]

Heavily reduced the test on this file and focused on unit testing serializing data type labels to NDJSON format. Generic data types tests the importing of NDJSON. I feel like it was a waste to double test this considering how long importing annotations takes when you consider set up and such

[Gabefire]

Also data types is marked as depercated

Ideally this is broken up into more smaller changes to derisk a large change (even though these are tests, better to change them in smaller units of work). Note to consider next time to prevent rework right now.
