influx setup: Error: instance has already been set up

## Issue

We cannot force the client to reset the influxdb config using this command
```
influx setup -f
Error: instance has already been set up
```
This is really weird as this problem still exists even if I remove, delete the files installed on macos using brew

```
brew uninstall influxdb-cli
brew uninstall influxdb
rm -rf /usr/local/etc/influxdb2
rm -rf ~/.influxdbv2

brew services restart influxdb

brew install influxdb-cli
brew install influxdb
influx setup -f
Error: instance has already been set up
```

**Version**: influxdb - 2.2.1

Reproduce `influx setup -f` with InfluxDB 2.2.1 after removing the Homebrew and local configuration paths listed in the report. Start at the CLI setup command and trace why the already-set-up state is not reset; done means the forced setup completes successfully after cleanup.
