## 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 master, branch-1.6, and branch-1.5.

## 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.
