When dragging and dropping a table from one instance of the application to the other, the tree structure representing the database was broken. We would show the 'Browsables' and 'All' nodes at the top level instead of the child nodes of the 'All' node. This happened because after dropping a table, we would reload the database structure and rebuild the tree structure but didn't notify the tree view in the main window about the update. This is fixed by this commit, so the main window's widgets are always notified about the new tree structure. See issue #1288.
