     bitbake: toastergui: Toastertables don't replace dash in cache key

     The dash character was being stripped from the cache key when we 
sanitise
     it for the memcache backend. This meant that we were getting a 
false hit
     on the cache and returning non descending results which are 
indicated by
     the dash prefix on the field name.
