Flaky test testLogExtraLogging fails occasionally

[wrigleyDan]

One of the tests in com.o19s.es.ltr.logging.LoggingIT - testLogExtraLogging - fails occasionally.

Running the test multiple times ultimately leads to a successful test run but it would be nice to have a more reliable and predictable test.

com.o19s.es.ltr.logging.LoggingIT > testLogExtraLogging FAILED
    java.lang.AssertionError at LoggingIT.java:626

It's not really clear to me what happens here. It seems to be related to nested hits (or skipping them during logging) as the two other cases with non-nested queries pass reliably. This likely came in 0078300 quite some time ago (cc: @aprudhomme, @nomoa). If there is no other way we might want to remove that code again.
