[fix][test] Fix flaky test NonPersistentTopicTest.testMsgDropStat, fo…
25c4b7c 
…llow up (#20401)

Fixes #20386

### Motivation

- the previous attempt #20387 to fix the flakiness wasn't effective

### Modifications

- improve the fix and rely on the fact that entryId is -1 when the message is dropped in the broker
  code: https://github.com/apache/pulsar/blob/091ee2504ffbe6ec98e354b76e7f4c045e1914aa/pulsar-broker/src/main/java/org/apache/pulsar/broker/service/ServerCnx.java#L1699-L1711

I added #20425 to get the actual root cause logged.

I was able to reproduce locally that this is the exception that happens first. The stats are missing for the producer.
