ondeviceready won't fire because plugin does not cleanup after itself properly when removed(?)

# Bug Report
>Originally reported at apache/cordova-plugin-device#125

## Problem
If an application has this plugin installed and, for some reason, it's not needed anymore and removed, `ondeviceready` won't fire anymore.
This seems to be caused by some leftover code... That's probably why the previous reporter mentioned the usual shenanigans of add/remove platform/plugins solved it.

### What is expected to happen?
The event should fire as usual, since it's seemingly unrelated to this plugin.

### What does actually happen?
`ondeviceready` never gets fired:

Logcat displays the following (easier to find if you filter logcat by the package name):

```

### Command or Code
```cli
$ cordova create sample-reproduction
$ cd sample-reproduction
$ cordova platform add android
$ cordova plugin add cordova-plugin-device
$ cordova plugin rm cordova-plugin-device
$ cordova run android
```

### Environment, Platform, Device

- cordova-android: 12.0.0 and 12.0.1
- plugin: 2.1.0 (as in clean install below), and also our actual project had it installed on 1.1.4, upgraded to 2.1.0, then realized it's not used and thus, got removed. We also removed other plugins and didn't had this kind of trouble.
- device: Android emulator, API 30

### Version information

Nothing besides what was described above seems relevant.

## Checklist

- [x] I searched for existing GitHub issues
- [x] I updated all Cordova tooling to most recent version
- [x] I included all the necessary information above

Reproduce the issue with the listed Cordova CLI commands on Android, then inspect the generated cordova.js and the removed plugin's www/device.js alongside the PluginManager log entries. Done means removing cordova-plugin-device no longer produces an unknown Device or class-not-found error and ondeviceready fires normally.
