[SPARK-20156] [SQL] [FOLLOW-UP] Java String toLowerCase "Turkish locale
bug" in Database and Table DDLs
### What changes were proposed in this pull request?
Database and Table names conform the Hive standard ("[a-zA-z_0-9]+"), i.e.
if this name only contains characters, numbers, and _.
When calling `toLowerCase` on the names, we should add `Locale.ROOT` to the
`toLowerCase`for avoiding inadvertent locale-sensitive variation in behavior
(aka the "Turkish locale problem").
### How was this patch tested?
Added a test case
