                 Key: YARN-11395

This bug was introduced with the YARN-1345 ticket what also caused a similar error called YARN-4411. In case of the YARN-4411 the enum mapping logic from RMAppAttemptStates to YarnApplicationAttemptState was modified like this:
- if the state is FINAL_SAVING we should represent the previous state

This error can also be occur in case of ALLOCATED_SAVING, LAUNCHED_UNMANAGED_SAVING states as well.

So we should modify the *createAttemptHeadRoomTable* method to be able to handle the previously mentioned 3 state just like in case of YARN-4411
