public function FeedsFileHTTPTestCase::testFeedsHTTPFetcherResultGetRaw in Feeds 7.2

Tests that FeedsHTTPFetcherResult::getRaw() always returns the same result for the same instance, even when caches are cleared in between.

Parsers can call this method multiple times on separate requests. When an import did not complete in one run, the source should never be refetched when calling getRaw().

When an import is restarted, a new FeedsHTTPFetcherResult is created and in that case the source *should* be refetched.
