Jonas Dreßler bda8ba5ed1 workspacesView: Only animate on show() when geometries are already set
Animating the window clones of the overview requires the fullGeometry
and the actualGeometry to be set, which they won't be when showing the
overview for the first time. So don't even try to animate the window
clones in that case because the geometries will still be null and
accessing them in workspace.js will throw errors.

The workspace views will still get the correct layout as soon as the
allocations happen because syncing the geometries will trigger updating
the window positions. Since animations are disabled for position changes
when syncing the geometry though, we won't get an animation and the
clones will jump into place. That's not a regression though since before
this change we also didn't animate in that case because the geometries
used were simply wrong (the actualGeometry was 0-sized as explained in
the last commit).

If we wanted to fix the initial animation of the overview, we'd have to
always enable animations of the window clones when syncing geometries,
but that would break the animation of the workspace when hovering the
workspaceThumbnail slider, because right now those animations are "glued
together" using the actualGeometry, so they would get out of sync.

The reason there are no errors happening in workspace.js with the
existing code is that due to a bug in Clutter the fullGeometry of
WorkspacesDisplay gets set very early while mapping the WorkspacesViews
(because the overviews ControlsManager gets an allocation during the
resource scale calculation of a ClutterClone, see
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1181), so it
won't be set to null anymore when calling
WorkspacesView.animateToOverview().
