[SRU] Adding app to app folders is broken

[Jeremy Bícha]

[Impact]
GNOME Shell introduced "app folders" in 3.8 (Ubuntu 13.10) with the default "Sundry" and "Utilities" folders, but there was not an easy way to configure them until now. (See http://www.omgubuntu.co.uk/2013/05/add-categories-to-gnome-shell-dashboard for the complicated way.)

GNOME Software has built-in support for editing app folders but this feature doesn't work in the 3.20 version. Although the feature is hard-to-find unless you know it's there from reading a guide on the internet, it's a nice improvement for Ubuntu GNOME 16.04 LTS.

These app folders are not used by Unity, LXDE or XFCE.

[Test Case]
0. Install the Software update, then log out and log back in to be sure the old gnome-software is not running in the background.
1. From Ubuntu GNOME (or at least from GNOME Shell), run the Software app.
2. Switch to the Installed tab.
3. Click the checkbox icon in the toolbar.
4. Select Aisleriot Solitaire
5. Click Add to Folder...
6. Click the + button and add a folder named Games. Click Add.
7. Click Add.
8. Open the Activities Overview.
9. In the bottom left, click the Show Applications button.
10. In the bottom center, click the All button.
11. Scroll down. You should see a Games folder with Aisleriot inside it.

[Regression Potential]
The patch to fix this comes from GNOME, where it was cherry-picked to the GNOME 3.20 branch (after 3.20.3).

Since the feature is completely broken currently and the patch will be picked up other distros shipping GNOME 3.20, the regression potential is low.

Two patches are needed:

This works good enough for me on Ubuntu 16.04 LTS.
