Snaps don't work unless pre-installed or user logs out and logs back in

Hi,

On newer versions of Lubuntu, snapd comes installed by default but no snap comes installed, unlike Ubuntu that comes with core.

If we install any snap after the installation, it will not integrate with the DE, i.e., it will not show up in the application menu. However, if I logout and log back in, then it is all fine. Regardless, we can fire the application via the terminal right after installation.

Relevant loose notes:
* If I do `snap list` it says no snaps are installed.
* `systemctl status snapd` returns inactive after installation
* Even if I install snap core, although the services changes to active state, I still need to logout and log back in.

Is there a way to snaps behave properly without the need to seed snap core into the installation process like Ubuntu does? It does not seem a behavior snapd should have.

Issues have been raised on the snapcraft forum:

Thanks for your time.
