Revert "Temporary fix for bad data pushed to Android test devices"

This reverts commit 9de609c874db42f31d4e81dd5a1dff94aec13b3d.

Reason for revert: been long enough?

Original change's description:
> Temporary fix for bad data pushed to Android test devices
>
> A change to Android asset deployment left some devices with bad data
> (but correct _VERSION files). Unless we force-push assets, test runs
> will continue to fail.
>
> Once all devices have had their assets re-pushed (and any bisection
> into the offending time period is concluded), we can revert this CL.
