Bug 1608302: Part 3 - Update the content process's service name in ContentDelgateTest; r=geckoview-reviewers,snorp

We'll want to make some changes to this test when we enable e10s-multi by
default, but for now we just need to update the name of the single content
process to reflect the naming changes that were done in part 1 of this
patch series.
