Description
This test verifies correct client behavior in the presence of
multiple providers.
Steps
1. starts up a client
2. starts two providers (X and Y) providing the same P property
3. X sets P to V1 and verifies that the client got it
4. Y sets P to V2 and likewise verifies in the client
5. Y sets P to NULL, the client verifies that P goes back to V1
6. Y sets P to V3, the client verifies P == V3
7. Y is removed from the registry, client verifies that P == V1
8. X is removed from the registry, client verifies that P == NULL
