[FLINK-3504] Fix join translation. Equality predicates may only reference
fields
Adapts the join translation rule such that only joins with proper equality
join predicates are translated.
A proper equality join predicate does only references fields, i.e., it does
not reference expressions.
Joins without at least one proper equality join predicates or with an
equality join predicate which references an expression are not translated.
