Two things: **Re-land**: Uninstall microbenchmarks before running them. Flakes in #153828 stem from adb saying the app isn't installed, but then failing to install wtih `-r`. Several other tests uninstall the app before trying to run it. Previous fix called uninstall between tests, but iOS takes 12 to 13 seconds to perform uninstall / install, which timed out the test. Just uninstall the one time since we only care about any lingering apps with different keys. Potential solution #153828 **Make things go fast** Instead of installing 21 different compilations of the same app to get results; compile and run them together. Locally on Mac+iOS, this should takes ~3 minutes instead of ~15 minutes.
