Re-enable flaky tests

Re-enable flaky tests that were disabled in March to see if they are
still flaky and collect logs (the old logs have been deleted already).

Re-enabled tests:
CronetUrlRequestContextTest#testShutdownAfterError
CronetUrlRequestContextTest#testShutdown
CronetUrlRequestTest#testFailures

One more flaky run from this morning.

The Java implementation is flaky. I will investigate.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/bd8d8d9b383908aa19602df995cdae3bf09ba484

commit bd8d8d9b383908aa19602df995cdae3bf09ba484
Author: xunjieli <xunjieli@chromium.org>

CronetUrlRequestTest#testFailures

CronetUrlRequestTest#testFailures() simulates callback
failures in each response step. However, the response step
is not updated in onFailed, so maybeThrowCancelOrPause()
will throw an exception again. This results in a flake
in the Java implementation.

This CL updates response step in TestUrlRequestCallback,
and adds two more tests to make sure throwing exception
or canceling does nothing in terminal callbacks (onFailed,
onCanceled, onSucceeded)
