Check for NULL pane window in wxAuiManager.
Check that the AUI pane has a non-NULL associated frame before checking whether it's shown. This should fix a crash which could happen when docking an undocked toolbar. Closes #10926. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@67741 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
