Fix original-file and patched-file tests.
Review Request #6212 — Created Aug. 8, 2014 and submitted
Some of the tests for the original-file and patched-file resources were failing
because it was trying to decode the responses as JSON. The problem was that one
of the GET test implementations was updated for the newbasic_get_returns_json
field but not another. I've made an equivalent change to handle it.
Ran unit tests.
