Commented Issue: ToLatestVersion test is failing after ContextKey change [490]

The tests "ToLatestVersion_use_connection_name_from_config_file" and "MigrateDatabaseToLatestVersion_invokes_migrations_pipeline_to_latest_version" are failing on my machine after pulling the ContextKey change. It seems that the history table has the ContextKey column but the model it contains does not have the ContextKey column, so we’re trying to add it but then this fails. I haven’t been able to figure out how we get in this state and it’s possible if I delete the test database and re-run that it will work, but I’d rather understand how it is we can get into this state so I have disabled the test and filed this bug.

Exception:
Test 'ProductivityApiUnitTests.DatabaseInitializationTests.MigrateDatabaseToLatestVersion_use_connection_name_from_config_file' failed:
System.Data.SqlClient.SqlException : Column names in each table must be unique. Column name 'ContextKey' in table 'dbo.__MigrationHistory' is specified more than once.

Comments: Scratch that - Looks like it might just be an upgrade scenario.
