  1. More asserts in listener_test for debuggability 

    We ran into a flake I could not debug so instead added assertions in
case it happens again.

Command was:

```
TEST_TMPDIR=/dev/shm/rocksdb COMPILE_WITH_UBSAN=1 USE_CLANG=1 OPT=-g SKIP_FORMAT_BUCK_CHECKS=1 make J=80 -j80 ubsan_check
```

Failure output was:

```
[==========] Running 1 test from 1 test case.
[----------] Global test environment set-up.
[----------] 1 test from EventListenerTest
[ RUN      ] EventListenerTest.DisableBGCompaction
