Bump workmanager `2.7.1` -> `2.8.1` to fix
```java
android.app.ForegroundServiceStartNotAllowedException: startForegroundService() not allowed due to mAllowStartForeground false: service eu.darken.capod/androidx.work.impl.foreground.SystemForegroundService
```
* wip
* Setup bugsnag only in gplay builds.
* Bugsnag does not support uploading mapping files or build information from library modules. This should be done from the application module which produces your APK instead.
* Only apply Bugsnag plugin for the right flavors.
* Run unit tests in debug, otherwise we run issues requiring api keys in the env
