Jonas Jenwald f61fb3e0f9 [MessageHandler] Re-factor the _onComObjOnMessage function to use early returns
When `ReadableStream` support was added to the `MessageHandler`, the `_onComObjOnMessage` function became more complex than previously.
All of the nested `if`/`else if`/`else` branches are now, at least in my opinion, making some of this code a bit difficult to follow. Hence this patch, which attempts to help readability by making use of early `return`s and `Error`s.

The patch also changes a couple of `var`/`let` occurences to `const`.
