Return constant reference from SWRaid_Info::get_uuid() (!94) 

Since the only use of SWRaid_Info::get_uuid() assign the returned value
this doesn't actually save any copy construction.  Do it for consistency
with the other get_*() methods in SWRaid_Info.

Closes !94 - Make more getter methods use return-by-constant-reference
