[SPARK-17956][SQL] Fix projection output ordering
## What changes were proposed in this pull request?
Currently `ProjectExec` simply takes child plan's `outputOrdering` as its
`outputOrdering`. In some cases, this might lead to incorrect `outputOrdering`.
This argument applies to `TakeOrderedAndProjectExec` too.
## How was this patch tested?
Jenkins tests.
