Subject: [PATCH 1/6] realmd: Set login format to null on start and update if
 invalid

We were checking an undefined property but that would lead to a a warning.
Instead we can consider the login format unset until is null, and in case
update it.

We shouldn't simply assume that st_shadow_helper_update() has been
called before paint() or that the pipeline was created successfully.

Subject: [PATCH 4/6] viewSelector: Don't set page parent during construction

gjs now aggressively garbage-collects objects that fall out of scope,
sometimes too aggressively:

 - we pass a child as construct property to StBin
 - as a result, the child's ::parent-set handler runs
 - when calling clutter_actor_get_parent() from that
   handler, the returned object is garbage-collected
   *before* the constructor returns (and thus the
   assignment that would keep it alive)

This is a bug on the gjs side that should be fixed, but we can easily
work around the issue by setting the child after constructing the
parent.

Subject: [PATCH 5/6] workspacesView: Don't set up MetaLater when unparented

We already do the check in the later handler, but if we got
unparented because the actor is destroyed, then the call to
get_parent() itself will trigger a (harmless but annoying)
warning.

Subject: [PATCH 6/6] workspacesView: Remove later on destroy

We are careful not to schedule the later when the actor is destroyed,
however it is possible that one is still pending at that point (namely
if the actor was never shown).
