[SPARK-18050][SQL] do not create default database if it already exists
## What changes were proposed in this pull request?
When we try to create the default database, we ask hive to do nothing if it
already exists. However, Hive will log an error message instead of doing
nothing, and the error message is quite annoying and confusing.
In this PR, we only create default database if it doesn't exist.
## How was this patch tested?
