Summary:
When ShellClient tears down, it needs to access RuleBook in order to
discard temporary rules. The problem is that WaylandServer outlives
Workspace and therefore so does ShellClient.
We can't guard against the case when RuleBook::self() is nullptr as it
is vital to discard temporary rules.
This change adjusts termination sequence so all shell clients are
destroyed before Workspace(and thus RuleBook) is gone.

Currently internal window test fails because several internal clients
outlive tests where each one of them was created. Given that the scene
doesn't specify the context object when it creates screenScaleChanged
connection, we may call windowGeometryShapeChanged on a deleted scene
object.
