[ML] [CI] DetectionRulesIT.testCondition failure

[davidkyle]

This test fails with the error:

Expected: "low"
     but: was "high"
	at __randomizedtesting.SeedInfo.seed([C579EF26625EB1F4:9CC01CBE66771FFC]:0)
	at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20)
	at org.junit.Assert.assertThat(Assert.java:956)
	at org.junit.Assert.assertThat(Assert.java:923)
	at org.elasticsearch.xpack.ml.integration.DetectionRulesIT.testCondition(DetectionRulesIT.java:120)

It appears the updated rules are not being picked up.

Reproduces fairly frequently for me ~ every other time:

./gradlew :x-pack:qa:ml-native-multi-node-tests:integTestRunner \
  -Dtests.seed=C579EF26625EB1F4 \
  -Dtests.class=org.elasticsearch.xpack.ml.integration.DetectionRulesIT \
  -Dtests.method="testCondition" \
  -Dtests.security.manager=true \
  -Dtests.locale=pt \
  -Dtests.timezone=Etc/GMT-7
