Fix SSR data passing

[Nkzn]

The ssr-data in HTML is not passed to props, because

• createPageRoute sets ssrData (in pagedata://) to page component props
• loadSSRDataFromTag sets ssr-data from HTML into memory (pagedata://)
• createPageRoute is called before loadSSRDataFromTag is called.
  • page component gets empty props

so, I moved loadSSRDataFromTag before createPageRoute.

test

examples/hello-world-ssr is same as SSR sample in the document.

1. run the sample
2. check the serverTime in HTML is passed to UI
