Public bug reported:
This is https://github.com/paradoxxxzero/gnome-shell-system-monitor-
applet/issues/449.
[Impact]
When the gnome-shell-extension-system-monitor is enabled, after the user's
session is locked then unlocked, then gnome-shell starts profusely logging
errors of this sort:

Aug 09 17:34:45 localhost gnome-shell[16993]: Object Gio.Settings
(0x55692427b520), has been already deallocated - impossible to access to it.
This might be caused by the fact that the object has been destroyed from C code
using something such as destroy(), dispose(), or remove() vfuncs
This will quickly fill the logs to the limits of what journald allows
(4G here) and make observing the log difficult in general (since the log
entries come in at the frequency of enabled monitors of the extension).
[Test Case]
1. apt-get install gnome-shell-extension-system-monitor
2. enable the extension in gnome-tweaks
3. lock the screen, wait a few seconds, then log back in
4. observe in journalctl --follow the stack traces for the extension. If you
disable the extension, the logging stops
When testing the fix, it is important that after upgrading to the new
version, you logout of your session then back in. Disabling/enabling the
extension does not seem to be enough.
[Regression Potential]
Regression potential is considered low since the patch simply moves the
initialization code into the enable() function (gnome-shell appears to
disable the extension on lock, and enable on unlock).
