Use class FakeServer in TestServerCreate.

In the current TestServerCreate, there are several problems:

1. The fake create() returns a server with no 'networks' field.
   The new_server is used to fake the created server which is
   supposed to be returned by create(), but it has a 'networks'
   field.

   They have the same name and id, but they are actually not
   the same server.

   As a result, when checking the return value from create(),
   'networks' is not checked.

2. The fake server is not accessable in the test functions.
   So each time a test function wants to get the server name
   or id, it has to use the constants defined in compute_fakes.

   This is not good. We should make the fake server accessable
   in all test functions to ensure they actually get the same
   server.

This patch fix them both by using the new class FakeServer to
fake a server.
