Component Props: coerce not working with default option in v1.0.20

[JosephusPaye]

Hi there, first I would like to say thanks for Vue, it is truly awesome.

I think I may have found a slight regression in Vue 1.0.20. It seems like the default option for component props is not passed through the coerce function in Vue 1.0.20. I had this working in 1.0.17 before I upgraded. See the Fiddles below for details.

Thanks

Vue.js version

1.0.20

Reproduction Link

Not working Fiddle (Vue 1.0.20): http://jsfiddle.net/5sH6A/292/
Working Fiddle (Vue 1.0.17): http://jsfiddle.net/0w62a9xx/1/

Steps to reproduce

See the Fiddles above.

What is Expected?

The prop default should be passed through the coerce function.

What is actually happening?

Only props that are specified in the template (and not defaults) are passed through the coerce function.

This looks like unintentional breaking change, but I don't think the behavior was ever documented.
As a workaround you can move default into the coerce function: http://jsfiddle.net/5sH6A/297/

I'm pinpointing a commit where the change has happened.
