Improve warnings for `melody-streams`

[cpatti97100]

When using melody-streams we sometimes get a very useful warning that says "Your component did not emit updates for 500ms".

Unfortunately when developing in the scope of a large application, it can be hard from time to time to understand where this warning is coming from.

Having the name of that component in the message would make this easier :)
Not sure about the internals but something like Function.name could come at hand.

Thanks!
