Show unlisted packages doesn't work
description
The "open package from feed" dialog has an option to show/hide unlisted packages from the search results when showing all versions of a package. However, it doesn't seem to be working as expected.
I've attached a screenshot of a package I own that has a few versions unlisted on the NuGet Gallery, but they never appear in this dialog. Looking at fiddler, the requests look the same for both queries (show unlisted & hide unlisted).
