Desktop: Resolves #3529: Fix AppImage Icon

[Jesssullivan]

Appends && update-desktop-database ~/.local/share/icons in addition to ~/.local/share/applications.
Checked on Budgie 20.04 LTS.

@Tiger862000 Does this work for you on Pop!_OS?

Resolves #3529- just double checked from a Pop VM:

@Jesssullivan and @laurent22
Sorry for the delay my PC was broken
It did not work for Pop!OS. Encountered the same problem with another application.
I installed Joplin as an Appimage.
As a workaround I had to select the icon manually using the AppEditor tool

@Tiger862000 Are you installing the AppImage via the official Joplin install script?
(Not AppImageLauncher or linter)

Icon installs correctly in a fresh PopOS VM.

I just installed version 1.0.242 via the official install script on the homepage, and the desktop icon wasn't installed.

What OS? Have you rebooted since installing?

[nullbasis]

Sorry, Ubuntu 20.04. I haven't rebooted, I don't usually need to do that when I install an appimage.

Hmm, cannot reproduce on 20.04-
perhaps try a sudo update-icon-caches /usr/share/icons/*?
