autodep regression by #2321

[heavywatal]

The option autodep=TRUE does not work since #2321 even with the simplest example as follows:

```{r, setup}
knitr::opts_chunk$set(cache = TRUE)
knitr::opts_chunk$set(autodep = TRUE)
```

```{r, src}
x = 1
```

```{r, dst}
y = 10 * x
y
```

Modifying x in src chunk should invalidate the cache of the dependent chunk dst, but is ignored in the latest version. I have tried different versions with pak::pkg_install("yihui/knitr"). Here are the results:

• OK: "yihui/knitr@v1.45"
• OK: "yihui/knitr@74bcff85455a9f92a3099abecba1a8d70ab0cfa4" 74bcff8
• NG: "yihui/knitr@f36e52cf39abba3be261e8e957c92587c63fa599" f36e52c
• NG: "yihui/knitr@v1.46"
• NG: "yihui/knitr" HEAD

FYI, adding cache-globals does not help invalidation.

```{r, dst2}
#| cache-globals:
#|   - x
z = 100 * x
z
```

@knokknok @atusy Could you take a look? Thanks!

Don't you need an initial dep_auto() to set-up the system?
