Align SDK with docs regarding session update for dropped events

[smeubank]

Problem Statement

Description

We've updated the docs (https://github.com/getsentry/develop/pull/551) to explain how we would like to handle event filter order, updating of sessions for dropped events and sending of session updates. We should check if we're aligned and adapt if necessary.

Solution Brainstorm

Here's the issue from the Java SDK where all of this started: https://github.com/getsentry/sentry-java/issues/1916

This issue has gone three weeks without activity. In another week, I will close it.

But! If you comment or otherwise update it, I will reset the clock, and if you label it Status: Backlog or Status: In Progress, I will leave it alone ... forever!
