Reverts #125927

context: b/300804374

Looks like a g3 fix might involve changing the names of widget on the customer app, and I am not sure if that would be the right approach forward. Putting up a revert to be safe for now.

When retrying to connect to the device during app launch, don't uninstall the app first.

Latest test flake for #120808:
https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8770202475999850785/+/u/run_hot_mode_dev_cycle_ios__benchmark/test_stdout

Shows that it uninstalled and then tried debugging and failed, which would make sense since the app wasn't installed anymore.
