fix: safe unregister SystemEventsBroadcastReceiver

[kollesnica1337]

📜 Description

• Add try-catch block in SystemEventsBreadcrumbsIntegration.unregisterReceiver() method
• Add test for this case

💡 Motivation and Context

I'm struggling with a crash in production that is quite tricky to reproduce:

It seems like in certain cases Android can kill SystemEventsBroadcastReceiver before SystemEventsBreadcrumbsIntegration calls unregisterReceiver() after app going background.

💚 How did you test it?

Added test case for this problem.
