fix: start context in MicronautRequestStreamHandler

[sdelamo]

Close: #1913

This PR changes so the MicronautRequestStreamHandler constructor starts the application context, and it invokes inject(this) for the handler to resolve injection points.

Is it worth changing MicronautRequestStreamHandler so it's exactly the same as MicronautRequestHandler?

It might make future comparison easier?

[timyates]

Actually, I think the code suggested above is more correct... It sets this.applicationContext which I cannot see happening in this PR?

[timyates]

Ahhh, I see... that happens in super.buildApplicationContext
