[SPARK-17996][SQL] Fix unqualified catalog.getFunction(...)
## What changes were proposed in this pull request?
Currently an unqualified `getFunction(..)`call returns a wrong result; the
returned function is shown as temporary function without a database. For
example:
```
scala> sql("create function fn1 as
'org.apache.hadoop.hive.ql.udf.generic.GenericUDFAbs'")
res0: org.apache.spark.sql.DataFrame = []
scala> spark.catalog.getFunction("fn1")
res1: org.apache.spark.sql.catalog.Function = Function[name='fn1',
className='org.apache.hadoop.hive.ql.udf.generic.GenericUDFAbs',
isTemporary='true']
```
This PR fixes this by adding database information to ExpressionInfo (which
is used to store the function information).
## How was this patch tested?
Added more thorough tests to `CatalogSuite`.
