Verify FormsTestCase forms submission result.

Add a missing GREYAssert to the |waitWithTimeout:| calls in
|waitForExpectedResponse:| and |waitForTabHistoryView|. Fix silently
failing tests (due to previously missing asserts) by implementing
/printformdata page to display the request method and body.
