Fix 6 failures in net unittests on Android

Fix 6 failures in net unittests on Android

These 6 failures are due to enable persistent session cookies:
1) Cookie without expiry time is persistent;
2) Cookie without expiry time is persistent so that the add/delete
command will be pushed back into the command list of cookie store.
