Remove the old fake server data.

The old fake server framework has be replaced with the new
class FakeServer, which is stronger in:
1. faking multiple servers with random names and ids
2. faking methods in a server
3. easier to use

So remove the old fake server data, and use class FakeServer
from now on.
