Can't install apps via clicking on apt url

[Alan Pope 🍺🐧🐱 🦄]

[ Description ]

Slashes are being appended to URLs passed to apturl, which it isn't prepared to handle.

[ QA ]

Test 1.

1. Open a terminal
2. Run `xdg-open apt://gnome-terminal'

You should see an error message if it is broken, and either a message about gnome-terminal being already installed or an installation prompt from apturl if it is not broken.

Test 2.

1. Click this link: apt://gnome-terminal

As above (assuming your browser is configured to correctly pass apt URLs over to the system's mimetype handler).

[ Regression potential ]

If the fix works, apturl will start working. A potential regression is that apturl is broken in some way that causes damage to systems.

[ Original description ]

Running latest artful.
Visit http://www.videolan.org/vlc/download-ubuntu.html
Click big orange "Available on the software center" button (which links to apt://vlc

Expected outcome:-

GNOME Software which would find vlc in the archive

Actual outcome:-

A dialog box appears
"Invalid URL: 'apt://vlc/' given, exiting
Invalid package name 'vlc/'"

See screenshot.

This bug was fixed in the package apturl - 0.5.2ubuntu13

---------------
apturl (0.5.2ubuntu13) artful; urgency=medium

  * AptUrl/parser.py: Strip trailing slashes that are added by xdg-open/gio
    and which make package names invalid. (LP: #1726327)
