Trevor Saunders 502b0f327c bug 1332690 - don't try and bind child docs to a shutdown DocAccessibleParent r=yzen
a BindChildDoc message can race with the parent process shutting down a tab.
The result of that is that RecvBindChildDoc() can be called on a
DocAccessibleParent that has already been shut down by the destruction of the
owning TabParent.
