If I add a throw error in the setup of a component (see playground example 1) I have the following confusing error: 

owl.js:1576 Uncaught (in promise) Error: An error occured in the owl lifecycle (see this Error's "cause" property)
    at handleError (owl.js:1576:31)
    at App.handleError (owl.js:5784:16)

    at ComponentNode.initiateRender (owl.js:2375:19)

I think that it was clearer before, i would like to see in the traceback that the error comes from the setup function of the component.

Another example: if there is an error in a template, (see playground ex2) we get the following traceback:

owl.js:1576 Uncaught (in promise) Error: An error occured in the owl lifecycle (see this Error's "cause" property)
    at handleError (owl.js:1576:31)

not very useful...
