Revert of Reenable AppleEventUtilTest.ValueToAppleEventDescriptor by removing the failing case.

Revert of Reenable AppleEventUtilTest.ValueToAppleEventDescriptor by removing the failing case. (patchset #1 id:1 of https://codereview.chromium.org/1399383002/ )

Reason for revert:
This caused failures on mac asan. See http://build.chromium.org/p/chromium.memory/builders/Mac%20ASan%2064%20Tests%20%281%29/builds/7109

Will put more info on the linked bug.

The asan failure is hopefully a good clue to fix the underlying flakiness :)
