Object St.Label, has been already disposed

[MeisterP]

Describe the bug This happens since a recent update of the extension from extensions.gnome.org

Sep 18 10:17:02 gnome-shell[2222]: Object St.Label (0x5651f9bad080), has been already disposed — impossible to set any property on it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs.
