Some appcache crash tests are flaky due to console messages
https://bugs.webkit.org/show_bug.cgi?id=185431
Reviewed by Geoffrey Garen.
Mark 3 tests that were written to test crashes as DumpJSConsoleLogInStdErr.
It is better to mark them as such than to changing them since they might no longer cover the crash reasons.
Rebase two other tests that might need further work to stop being flaky.
