Hi Henrik, before hooking up the new statistics interface, we should make sure
that the default values of the stats are the same as the previously used values.
PTAL.

I updated this CL with a small change to avoid overwriting the default values
when getting metrics was unsuccesful (for example when the AEC is disabled or
metrics on the AEC are disabled). Otherwise we would just overwrite the default
values. Could you have another look?
