Wait for any pending realtime task to complete before disabling datasource (#3757) 

Noticed this in our internal testing, sometimes realtime index tasks in
kafkaIndexing service can get stuck waiting for handoff if datasource
is disabled before there task completion.
This is a workaround to ensure integration tests do not hit this case
until https://github.com/druid-io/druid/issues/1729 is fixed.
