codership/wsrep-lib#13 Fix dbsim to deal with provider generated server id

Browse Source 
Dbsim has internal map of server objects for SST simulation.
This was mapped using server_id, which is not available
anymore when server object is constructed. Changed the dbsim to
use server name instead for internal mapping.
