[SPARK-13473][SQL] Don't push predicate through project with
nondeterministic field(s)
## What changes were proposed in this pull request?
Predicates shouldn't be pushed through project with nondeterministic
field(s).
See https://github.com/graphframes/graphframes/pull/23 and SPARK-13473 for
more details.
This PR targets both master and branch-1.6.
## How was this patch tested?
A test case is added in `FilterPushdownSuite`. It constructs a query plan
where a filter is over a project with a nondeterministic field. Optimized query
plan shouldn't change in this case.
