[Cronet] Make metrics reporting happen after terminal callbacks.

This CL re-arranges metrics report to happen after terminal callbacks
(UrlRequest.onSucceeded, onCanceled, onFailed). This CL adds additional
tests to check that RequestFinishedInfo callback is strictly after UrlRequest's terminal callbacks.

This CL also fixes a bug where if we get an exception from embedder
(onCallbackException), we did not set RequestFinishedReason
to FAILED. testOrderFailedRequestJava is a regression test.
