If ReplaceCommand with ignorePrevValue=true is executed on a backup owner node which has not the entry in the container (for example because the state transfer was not completed yet), the EntryWrappingInterceptor/EntryFactoryImpl won't put it the command's context. Then, in the ReplaceCommand.perform() the entry is not replaced and the command fails.
The command on primary owner succeeds as it does not check whether the responses are successful.
