Elasticsearch tests: Recreate container for each test suite

Since Change If3f8d914d5f there are multiple index configs executed in
different config suites in the tests and that means the ElasticContainer
will be stopped after each suite completes. Handle that by always
recreating the container at the start of a suite.
