If the app project had android.enableR8.fullMode=true (default true with AGP 8+) the stub classes that start with "misconfigured" would removed. This would cause a "could not be instantiated" exception to be thrown when initializing as the code assumes there would be some class that implements the interface, an example INotificationsManager. The stub classes are removed in the minification step since they are created with reflection via ServiceProvider.getService(). Anytime reflection is used there you must add special Proguard consumer rules to keep those classes. In this case we only need to make sure the class itself exists, so we use "<init>(...);" in the rule which means keep the default constructor.
We need to ensure the exception is created at the time of the call instead of upfront. As the stack trace reported by the exception is when it is instantiated.

Description
One Line Summary
Fix "could not be instantiated" exception when; some modules are omitted AND
android.enableR8.fullModeis enabled.Details
This also fixes the stack traces reported when attempting to use a module that wasn't included 2b2e76a
Motivation
This results in crashes when these two conditions are meet. SDK should include all Proguard rules so app developers don't have to manually add them to avoid issues like this.
Scope
Only effects keeping a bit more code when minification is enabled.
Testing
Manual testing
Tested with the included example app with the following modifications:
android.enableR8.fullMode=truetoExamples/OneSignalDemo/gradle.propertiescom.onesignal:OneSignal:5.1.15withcom.onesignal:core:5.1.15inExamples/OneSignalDemo/app/buidle.gradleReproduced the crash reported in issue #1969 and ensured it no longer happens after the change. Tested on an Android 6.0 emulator.
