calendar: Use connectObject on _sectionList

Browse Source 
This prevents _sync() being called after actor destruction (since actor
destruction became more reliable in mutter@3d94c7cc2) and so eliminates
this shutdown error:

```
(gnome-shell:35197): Gjs-CRITICAL **: 16:31:02.769: Object .Gjs_ui_calendar_Placeholder (0x559ed6e547e0), 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.
