repo_resolve() for different snapshot date returns the same url

[pawelru]

I would expect different urls will be returned for different dates

I think this is caused by a recent PPM update, and maybe it is an intentional change, maybe it is not. I reported it to PPM.

[gaborcsardi]

Yeah, unfortunately they changed the format of this, so this breaks pkgcache.

Now you can use the dates directly, e.g.
https://packagemanager.posit.co/cran/2019-07-12
and it should resolve to the previous snapshot if there was no snapshot on that date.

[pawelru]

OK thanks for confirmation. I think I can handle this by parsing url string on my own.

[gaborcsardi]

Will fix soon, but it'll probably take a couple of days.
