--improve the new worksarounds in order to always
apply the activities that a view and its windows are
present when the workarounds were triggered from
kwin faulty behavior. The kwin faulty behavior is
that when any activity is paused then all Latte::Views
become hidden and lose their activities references.
The workarounds are timers that when they trace
a faulty visible state !visible are restoring the
normal behavior to views.
