shiny_prerendered documents execute in wrong environment

[wch]

For example, this document will read args and output_file from the environment created by shiny_prerendered_html()'s invocation.

---
title: "Untitled"
output: html_document
runtime: shiny_prerendered

---

```{r}
args
output_file
```

The result looks like this:

The culprit is this new.env():
https://github.com/rstudio/rmarkdown/blob/6def14c/R/shiny_prerendered.R#L125

Perhaps it should have parent=globalenv()?
