[bug] conan download pkg/version@user/channel#randomrev downloads latest

Latest 1.20, Windows 10, python 3.7

With revisions disable this doesn't fail (it should). And worse, it creates an entry with revision randomrev in the cache.

Also, it seems that it is not possible to conan download a package with a given package revision.

It is important to follow up here, this could be problematic or show underlying problems, for example if using lockfiles, like the locked version is not the one being retrieved.
