[HIVE-15584] Early bail out when we use CTAS and Druid source already exists

Description

If we create a Druid source from Hive with CTAS, but a Druid source with the same name already exists, we fail (as expected).

However, we bail out when the query for creating the query results has already been executed.

We should bail out earlier so we do not execute the query (and thus, launch the Tez job, etc).
