[CI] JdbcSqlSpecIT and JdbcCsvSpecIT initializationError

[henningandersen]

My PR build failed with initializationError in above tests due to a missing directory. This seems to have happened once before on August 14th. I can reproduce this locally too.

The error is:

org.elasticsearch.xpack.sql.qa.security.JdbcCsvSpecIT > initializationError FAILED
--
java.nio.file.NoSuchFileException: /var/lib/jenkins/workspace/elastic+elasticsearch+pull-request-2/x-pack/plugin/sql/qa/security/without-ssl/build/classes/java/test

I can reproduct this locally by doing:

./gradlew :x-pack:plugin:sql:qa:security:without-ssl:clean

and then

./gradlew :x-pack:plugin:sql:qa:security:without-ssl:integTestRunner

fails. The test directory referenced above does not exist.

If I instead invoke the check task, it works OK and the directory is created.
