Disable ObjectElementsViaHttp test when MimeHandlerView is OOPIF-based.

This CL temporarily disables one of
SavePageOriginalVsSavedComparisonTest tests to enable landing of
a change to //testing/variations/fieldtrial_testing_config.json
that enables MimeHandlerViewInCrossProcessFrame everywhere in
preparation for shipping this feature to the stable channel in M76.

The test failure seems mostly understood and the test should be
re-enabled within a week or two.
