[SPARK-1955][GraphX]: VertexRDD can incorrectly assume index sharing
Fixes the issue whereby when VertexRDD's are `diff`ed, `innerJoin`ed, or
`leftJoin`ed and have different partition sizes they fail under the
`zipPartitions` method. This fix tests whether the partitions are equal or not
and, if not, will repartition the other to match the partition size of the
calling VertexRDD.
