Incorrect value saved in variant_metric_info.receivers

I've only seen this issue once out of 50 or so pushes, and for the android variant.
The value saved in variant_metric_info seems to be that of the first batch sent to GCM, either ignoring or overriding the sum of all batches. (receivers persisted is 1)

There was only one push going out at that time so its not mutliple pushes mixing up in the log.
