[CI] :plugins:repository-s3:s3Fixture failure on 6.4

[romseygeek]

Starting up the Amazon S3 fixture fails with the error message:

Exception in thread "main" java.lang.IllegalArgumentException: bucket null is already registered

See https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+6.4+third-party-tests-s3/10 for an example. It looks as though this particular job has never passed?

@vladimirdolzhenko Does it ring a bell to you? I'm wondering if #32353 should be backported to 6.4

[vladimirdolzhenko]

@tlrx yes, you're right, did we have third party tests for 6.4 before ?

[tlrx]

@vladimirdolzhenko I'm not sure when they were added (@fatmcgav might know). Anyway, would backporting #32353 fix the test?

So the CI jobs for 'third-party' testing on S3 for master and 6.x were added on 26th June via https://github.com/elastic/infra/pull/5680.

This was expanded to cover 6.4 and 6.5 as part of https://github.com/elastic/infra/pull/7604, as confirmed in https://github.com/elastic/infra/issues/1063#issuecomment-434221017 with @jasontedor
