Public bug reported:
I re-created a flavor that is the same 'flavorid' on before and after.
After re-creation, the flavor value of the instance, that created by the
'flavorid', was changed to the new flavor value.
Currently, the flavor value of the instance is refer to 'flavorid'. In
this case, it should be refer to 'id', not 'flavorid'.
In database scheme, id is really unique but flavorid is perform the
conflict.
