Revert of [autofill] Sync server card and address metadata. (patchset #8 id:820001 of https://codereview.chromium.org/1110833002/)

Reason for revert:
Chrome Stability sheriff here--I suspect that this is causing crashes on Win, Mac and Android (maybe everything); see https://code.google.com/p/chromium/issues/detail?id=497659#c6
