Need to test scenarios where vdb source translators are changed.

I encountered a couple confusing scenarios where I changed the translator on a vdb source, but had no change on execution in designer. We need to test to ensure that vdb is picking up translator changes as expected.

Scenario

• Import a source Model (in my case it was SF).
• Create a VDB and add the source model to it.
• Deploy VDB, execute query to verify can query ok.
• Change source translator in VDB to 'loopback'. Save VDB
• Redeploy VDB, then run query. Loopback was expected, but I still got SF data back

1) the scenario above changes the translator in the VDB, but there is still an annotation in the source model with 'translator=salesforce'. So they are in conflict.

2) Changed the source model annotation translator to 'loopback', resync'd the vdb, redeployed and queried again. Still got SF results instead of loopback. The re-deployment is not picking up the translator change.

3) Finally, in the server view, manually 'un-deployed' the vdb. then went back to model exployer and deployed again. Then I got loopback results.
