Fix raw data regression test.

[aaronweeden]

Description

This PR fixes intermittent failures of the raw data regression test. The failures are due to the fact that for the fresh_install test mode, the mapping of id to name in the modw_supremm.exit_status table is non-deterministic. As a result, requesting the rest/warehouse/raw-data endpoint with the filters[exit_status] parameter set to specific input values does not always produce the same output rows across multiple CI runs. This PR changes the test to instead filter by application, which reliably produces the same output rows due to a deterministic mapping of IDs to application names in modw.application across multiple runs.
