Previously, when creating a new database, the CatalogOpExecutor would create an HMS Database object, issue the HMS createDatabase call, and then create a Catalog entry from that same Database object. The resulting Catalog entry would be missing certain fields that are auto-created by the HMS itself, most importantly the location field. The code for CTAS seems to have contained a workaround for this issue ever since catalogd was first introduced: rather than using the location stored in the Db object, it would re-fetch the Database from HMS. Now that this is fixed, that workaround could be removed and some code simplified. A new test verifies that a newly-created database has the appropriate location, and existing CTAS tests verify that functionality didn't regress.
