[snap] Wrapper script might create duplicate launcher entries for chromium_chromium.desktop

[Olivier Tilloy]

When installing the updated deb package that transitions to the snap, if the snap was already installed and its desktop file already pinned to the GNOME Shell / Unity launcher, and if chromium-browser.desktop (from the deb) was also pinned, the /usr/bin/chromium-browser wrapper script will rewrite chromium-browser.desktop to chromium_chromium.desktop, but it doesn't check whether there is already an entry for it in the favorites, so it might result in duplicated entries.

This is not visible to the user because both GNOME Shell and Unity launchers appear to have some logic to filter out duplicate entries. Still, it would be nice to not add duplicate entries.

multiple copies though are visible in the default browser selector of preferred applications in xfce settings...

Darko, that's a different issue, which I think has the same root cause as bug #1847048, feel free to comment there to explain the problem.
