**Describe the bug** NPE When `OpReadEntry.create()`. When the `ledgerId` in `ManagedLedgerImpl.ledgers` is null. the call to `OpReadEntry.create()` will trigger `readEntryFailed` callback but this time the cursor of `OpReadEntry` is still unseted. More seriously, it will make the variable `havePendingRead` can't become true again. **To Reproduce** It's quitely hard to reporduce the problem. In our environment, we shutdown all bookkeepers meanwhile, has the probability to reporduce it. **Screenshots**  -- This is an automated message from the Apache Git Service.
