I installed release 0.1.1

I deleted the .ucx folder
I deleted the workflows
I deleted the dashboards
I did NOT delete the tables in the ucx database

I installed release 0.2.0
I ran the "assessment run" workflow

All of the tasks completed successfully, except for the final "assessment_report" task

The "External Locations" widget failed with:
[TABLE_OR_VIEW_NOT_FOUND] The table or view hive_metastore.ucx.external_locations cannot be found. Verify the spelling and correctness of the schema and catalog. If you did not qualify the name with a schema, verify the current_schema() output, or qualify the name with the correct schema and catalog. To tolerate the error on drop use DROP VIEW IF EXISTS or DROP TABLE IF EXISTS.; line 4, pos 5
