Reverts: flutter/flutter#154374
Initiated by: jtmcdole
Reason for reverting: A different benchmark was using the microbenchmark parser and timing out.
Original PR Author: jtmcdole
Reviewed By: {zanderso}
This change reverts the following previous change:
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.
