Oilpan: have ScriptStreamingTest correctly trace its PendingScript.

Oilpan: have ScriptStreamingTest correctly trace its PendingScript.

As testing::Test is not on the heap, accommodate Oilpan by wrapping up
ScriptStreamingTest's PendingScript (a part object containing a Member)
inside an object that is on the heap & use a Persistent to refer to it
from ScriptStreamingTest.
