Scoop doesn't extract .tar.* archives fully

[Calinou]

If one writes an URL to a .tar.* archive (such as .tar.gz) in a manifest's url field, Scoop will download it but will only extract it to an xa-tmp.tar file. To fix this, 7-zip needs to be called twice on those files, so that the .tar is unpacked to its actual data.

@Calinou, it seems that extraction should work.

Double extraction logic is already there: https://github.com/lukesampson/scoop/blob/2224da82f8a786b8ae9c203c67924b4c6ef2c652/lib/decompress.ps1#L24-L28

There are also a few manifests that point to .tar.gz archive, for example up: https://github.com/lukesampson/scoop/blob/a2fed1855865d3d2d8f0eb6564c52163db650177/bucket/up.json#L7
I tried running scoop install up and it worked fine for me.

@Calinou Is it OK or is some fix needed?

I tried updating Scoop but can still reproduce the issue. This is the manifest I'm trying it with:

{
    "homepage": "https://sourceforge.net/projects/freecs-1-5/",
    "description": "Free software reimplementation of Counter-Strike 1.5 running on FTEQW",

    ],
    "notes": [
        "Optional but recommended: To avoid missing assets, place an Half-Life installation's \"valve\" folder in:",
        "",
        "\t$persist_dir\\"
    ]
}

Console log:

Notes
-----
Optional but recommended: To avoid missing assets, place an Half-Life installation's "valve" folder in:

        C:\Users\Hugo\scoop\persist\freecs\

Those are files I can see in the app directory after installing (the file size matches the second file in the url array):

This is due to this .tar.gz has a diferrent name in inner .tar, and is fixed in #3204 079c4a5
