[SPARK-18921][SQL] check database existence with Hive.databaseExists
instead of getDatabase
## What changes were proposed in this pull request?
It's weird that we use `Hive.getDatabase` to check the existence of a
database, while Hive has a `databaseExists` interface.
What's worse, `Hive.getDatabase` will produce an error message if the
database doesn't exist, which is annoying when we only want to check the
database existence.
This PR fixes this and use `Hive.databaseExists` to check database
existence.
## How was this patch tested?
