Autofocus textarea every time message input component is rendered

That includes when switching channels.
I got this requirement from our designer after some user complaints and I think it makes sense.
Also I see that this behavior is already present in the react demo.

This makes sense, but I'm not sure when we can add this improvement.

[ilyakonrad]

Why not?

[szuperaz]

I don't know when I will have the time to do this. We're currently busy with other tasks on the SDK.

[ilyakonrad]

I can try to contribute if you don't mind, it doesn't sound like a big task.

We're accepting contributions, so feel free to give it a go.
