dash: Connect before destroying

Browse Source 
Since commit 7bd98f3f5f animateOutAndDestroy() destroys
the placeholder right away when animations are disabled. Connect to the destroy signal
before calling the function.

This fixes the following error:
Gjs-CRITICAL **: 16:51:35.195: Object .Gjs_ui_dash_DragPlaceholderItem (0x55b9a946da20),
has been already disposed — impossible to connect to any signal on it. This might be
caused by the object having been destroyed from C code using something such as destroy(),
dispose(), or remove() vfuncs.
