[SPARK-5534] [graphx] Graph getStorageLevel fix
This fixes getStorageLevel for EdgeRDDImpl and VertexRDDImpl (and therefore
for Graph).
See code example on JIRA which failed before but works with this patch:
[https://issues.apache.org/jira/browse/SPARK-5534]
(The added unit tests also failed before but work with this fix.)
Note: I used partitionsRDD, assuming that getStorageLevel will only be
called on the driver.
**QUESTION**: Please look at GraphSuite's test("cache, getStorageLevel").
It succeeds, but should it? After constructing the graph, vertices are cached,
but edges are not.
CC: @mengxr (related to LDA PR), @rxin @ankurdave Thanks in advance!
