Todd Lipcon 7c0450d6d4 IMPALA-7439. CREATE DATABASE creates a catalog entry with missing location ...

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.
