Revert of [GCM] Start GCMChannelStatusSyncer when GCM is disabled (patchset #2 id:20001 of https://codereview.chromium.org/653843003/)

Reason for revert:
Reverted due to that the fix is not complete. Will fix one more issue we find and reland the patch.

Original issue's description:
> [GCM] Start GCMChannelStatusSyncer when GCM is disabled
>
> We need to start GCMChannelStatusSyncer when GCM is disabled in order
> to poll the server to find out when it is reenabled.
>
> Also if server returns empty response, we should not treat it as error
> and trigger the backoff logic.
>
> BUG=423415
> TEST=new tests added
