Revert 203587 "Move CheckInstall to device status and fail on lo..."

Broke android tests.

> Move CheckInstall to device status and fail on low install speed and battery.
> 
> Removes the recently added CheckInstall step and moves the checking to the
> device status check step. Recently, devices will install very slowly causing
> tests to fail with device problems. We have also seen battery issues. The new
> device status check step will fail if any devices install unreasonably slow
> (i.e. < 800 KB/s) or have critically low battery level (i.e. < 5%).
