[SPARK-22333][SQL]ColumnReference should get higher priority than
timeFunctionCall(CURRENT_DATE, CURRENT_TIMESTAMP)
## What changes were proposed in this pull request?
https://issues.apache.org/jira/browse/SPARK-22333
In current version, users can use CURRENT_DATE() and CURRENT_TIMESTAMP
without specifying braces.
However, when a table has columns named as "current_date" or
"current_timestamp", it will still be parsed as function call.
There are many such cases in our production cluster. We get the wrong
answer due to this inappropriate behevior. In general, ColumnReference should
get higher priority than timeFunctionCall.
## How was this patch tested?
unit test
manul test
