Carlos Garnacho 7095ef05e1 workspacesView: Skip relayouts during destruction
The WorkspacesView may be scheduled to be destroyed during
relayout, and despite that go through the allocate() vfunc.
When that happens, the ::destroy handler is called early,
so the WorkspacesView clears this._workspaces in result.
When vfunc_allocate() is called, various paths rely on the
workspaces array being still populated, which is not the
case.

The existing check at vfunc_allocate() for the WorkspacesView
having no children is insufficient, since children are destroyed
as a result, not beforehand.

This results in the following warnings when going out of
overview:

JS ERROR: TypeError: workspace is undefined
_getSpacing@resource:///org/gnome/shell/ui/workspacesView.js:218:13
vfunc_allocate@resource:///org/gnome/shell/ui/workspacesView.js:344:18

_handleEvent@resource:///org/gnome/shell/ui/swipeTracker.js:173:26
@resource:///org/gnome/shell/ui/init.js:21:20

This always happens through the _updateWorkspacesViews() paths, so there
is a new WorkspacesView taking over and the one being destroyed should
silently go away.
