svx: remove nonsense exception throwing code

Commit 60f11adb added code to
AccessibleShape::getAccessibleStateSet() that tries to retrieve some
state from the parent, but the implementation of the base class
AccessibleContextBase::getAccessibleParent() throws if it is already
disposed, which is the condition checked just before, so surely
this doesn't have any other effect than throw DisposedException,
except possibly in the mpText == null case which is already
handled in the other branch with identical code.
